MAKE SURE TO CHECK PAGE THREE THERE ARE ADDED SETTINGS.

I’ve been toying around with this for awhile now. The cable modem/DSL tweaks, and the PPPoE tweaks are Great, but you can get anywhere from 100kbps to 200kbps more out of your connection if you add this setting in the same spot in your registry as the string value MaxMTU..
the new string for cable to start is string value.
MaxMSS and set it to 1460 or lower,
MSS stands for Maximum Segment Size.
This has increased my connection by 190kbps.
I also have had the opportunity to play with this on a PPPoE DSL Connection this one takes a little more playing around with.
lower the MaxMTU to 1492 and put the
MaxMSS at about 1420 to start esp. if your on a Mindspring connection you don't want to blow up IE. Give it a try and if your not sure about the size just make it smaller than the values iv got here you should see a noticeable improvement right away. I know I have.
The OS that this has been tested on iswin95, win98 and win98SE IE 5.01 IE 5 and IE 4.01 sp2 and now IE5.5.
Let me know your findings Thanks.
This info comes out of the windows big book, and regedit.com and a whole bunch of other area’s now, and with the help of other members on this board along with the speedguide group. Without the members and themselves this topic would not exsist’s
let me know on the board if this helped your connection

I also have the MSS values written in patch’s at http://microsyspro.com under a link called speed up your internet connection with MaxMSS

Had to edit:ADD ON
The server for the web site above had just been replaced and is going threw growing pains if you are not able to get there then go to this alternat site http://humlog.homestead.com/nicksconsulting/
Sorry for any inconvenience

I was playing with MaxMSS a couple of years back... At one time it was in the patches, however everyone jumped all over me that it is a bogus entry. I couldn't find documentation from MS on the exact syntax, besides MSS seems to be calculated automatically, so it's been thrown out.

If anyone finds reliable information (from MS) on the location of the entry in the registry, let us know.

Well.....I tried it and got about a 20% speed increase downloading, touching almost 50% at times, but this was during peak hour so it varied. Still, that's excellent http://www.speedguide.net/ubb/wink.gif Thanks for the tip!

osoft posted read carefully some connections it works infact a good amount of them it works on but if its two high the connection drops MaxMSS is based on what there connection is not a exact value.

The links below are directly from Microsoft based on windows 2000 because the protocols are so Close to win98SE, That they just did things like they always do, and that’s when a new product comes out. The old library goes out the window. So if you believe everything from Microsoft then it may be real possible to get rid of the DefaultRcvWindow if I read it correct MSS can make up the difference. I'm not saying but you asked for some type of proof well if someone has a different Microsoft please let me know. Man I feel like I've been through a re-cert. test
Note: there is one thing that bothers me about all this that if the MTU drops across a network the MSS could stay up and could cause a real slow down there's supposed to be an article at NASA about a high MSS over MTU but I'm not quite sure about the OS they had.

All of these articles talk about MSS (Maximum Segment Size)... I know exactly whaat MSS is, as I said I've used it in previous patches, my question was:

What is the exact syntax of the entry in the Windows Registry according to MS ?

Hey. I added MaxMSS with a value of 1460 to all the 000X (you said put it in the section with MaxMTU, i have like 5 http://www.speedguide.net/ubb/smile.gif) in HKLM,System\CurrentControlSet\Services\Class\NetTrans\ and i noticed no increase or decrease. I have pretty poopy RR in upstate NY. My test file, before i added the keys in it was 70KB/sec, after was 69KB/sec. Did I do it right, do I add MaxMSS to al lthe 000X keys that have a MaxMTU setting in it? my maxmtu is 1500 and the maxmss is 1460, or do i just add it to one of them, or what?

help!

I sent you a email on this.
Do the ping thing speed guide has a good method for this in the advanced area to make certain your MTU String value is correct
if the MTU is to high MSS won't work and in some case's even though the MTU is correct you may have to lower it to get the Max out of MSS their are all sorts of opinions on MSS
out on the web that this setting can throw you a curve. with this one its not an exact science. make sure all your hardware is correct and that you don't have some type of software interfering with your connection 70 and 69k is real bad see if the cable company can put a booster on the line
well I hope what I sent helped let me know
but I really think theirs somthing else causing your bad connection

HKLM,System\CurrentControlSet\Services\Class\NetTrans\000x and so on. as a string value called MaxMSS with a starting size of 1460
higher or lower depending on the system this has been tested on win98SE win98 win2000 by me on my connection and it seems to work well with the equipment I have

I have just finished messing around with the various settings on my computer.
I am using WinME with cable modem.
I have found that changing my MaxMTU setting from 1500 to 1496 and then using the MaxMSS setting of 1460 produced the best results for downloading.

Nice to see a fellow floridian here Phillip, I'm in clearwater formerly from Manchester, England.

If you're also using a 56K modem, you should not add those settings to the 000x keys that your modem uses. Modems work better on 576 MaxMTU.

As for not improving your download from 70KB, it may be that you're capped at 70 in which case that is the most you can get out of your cable/dsl. I am capped at 50KB so don't complain :-) But before I added the MaxMSS, I was only getting 35-40 offpeak. Now I'm getting close to 50 at peak hour times.

My best advice to you is read everything you can in the speed guide it has already been laid out in the advanced tweaks and in the rest of speed guide. If your the faint of heart and don't no how to back up your registry yet then thats a good place to start other wise I just have to type everything over and its been done.
It would help if you told us what type of connection you have and the speed your getting now (kbps)
Good luck learning you should get allot from here also put in the downloadable tweaks that are here they make a big difference right away
well been a long day I'll get back to this today 1am

I hope the email that I sent helped it is a little more involved to fine tune the setting
let me know if it helped or not.
and like Clover said you may have gotten to your cap already. But I alway's think there's room for improvment.
For though's of you getting results please post them including the setting you finnaly ended up with this could be a big help. Remember this one may not be an exact science
we may even have to go as far as who your ISP is.
Thanks

Hi I don't no
I have some of the same feelings. The point is has anyone been able to say it really dosn't work.
Ya its been going back and forth but maybe if we get a better handle on MSS if we can and finally get some truth out of Sun, Microsoft, and IBM, whom all three are useing it in some way for stability and speed in there networks
even NASA has a paper written on it for use on there Unix machines only they reverse the settings.
Here I got one: this is the RFC 879 taken right from off of Microsofts site in reference to win2k where they give a value for use of MSS with MTU and then point to the RFC number above and say that it can even be used in some cases to replace the DefaultRcvWindow string
Ya I had to go back and look that one up again. since we're basically talking Windows I'll stay out of SUN or IBM
Do we keep it or not. I say it works but all networks are not the same and that it should be put in a system where the person is willing to take the time to tune it to their individual networks because thats the only way it will work the default for MSS is 40 less than MaxMTU thats the starting point. the legal start limit according to Sun and Microsoft is a 576 MTU and a 536 MSS now we are all pressing the limit
here is the link to RFC 879

Dan, the email was like kinda long and confusing, i didnt read 100% of it, probably like 75%.

I tried my mtu at 1496 and mss at 1460, no noticable difference. happypuppy.com I get good speeds like 300KB/sec, but its in long island, im in upstate ny, so its only like 150 miles away, so unless a site is 200 < miles away im stuck with poop speeds http://www.speedguide.net/ubb/frown.gif I use RR in upstate NY (Binghamton area) and in our local newsgroups people have slow speeds too

We have been running about 50/50 on this between the email and the post here. It seems that people with real good connections or real bad connetions "ARE NOT" getting any benifit from this setting so keep in mind that this won't work for everyone.

07-18-00, 01:52 PM
MSS by all the rules according to whats in print from microsoft that you can get info on is that it should be set to 40 less than your MTU now this won't applie for a true Unix machine NASA has theres set MSS 1530 and MTU 1500 it all really depends on how good a connection you have to the server at your ISP I run a higher MSS because my ISP has a c%#$% connection to the backbone. so if you get a better result with it up go for it all networks are not the same at the start point example: my setting a month ago had been great MTU 1500 MSS 1476 this month because they changed the loop and added a whole mess of newbe's now my MYU 1492 MSS 1472 go figure this is probably why next week i'll be on my new DSL line with 1500 down and 400 up
good luck with it its been mixed

Look, MSS is a function of the MTU. I would be very interested in reading ANY source on an ethernet network that has an MSS greater than the MTU.

The reasoning is this:

The Open Systems Interconnect (OSI) model provides 7 layers which govern how information flows between systems. By using this model to determine what has to happen at the various layers, rather than how it happens at each layer, it remains vendor non-specific. Which means a NIC card from 3Com, and One from Linksys can effectively communicate because BOTH adhere to certain protocols, what chipset each uses to do this is immaterial. As long as the NIC obeys the protocol requirements, the other device can understand the information sent.

There are seven layers, from top down, they are:
Application
Presentation
Session
Transport
Network
Data-Link
Physical

Information flows down from the layers above to the Transport layer, where the data is broken up into segments. In addition, 20 bytes of information allowing correct reassembly at the other side of the connection is added.

Below that, at the network layer, the segmented data is then encapsulated in a packet, and IP addressing and other info is added.

Then, the newly formed packet goes down to the Data-Link Layer, where it is embedded in a frame, with hardware (MAC) addressing, and some other info.

This FRAME, is what is actually sent out on the wire, in the form of bits. Ethernet specifications call for a 1500 byte frame. This maximum size of frame is called the MTU, or Maximum Transmission Unit. Since you must add both the MAC and IP addressing for WAN communication, the MSS (Maximum Segment Size - from the transport layer, remember?) must be small enough to allow both the IP and MAC addressing fields to be added.

Thus, the MSS must be less than the MTU.

Now, the MAC address is 48 bits in length. You need a source and destination hardware address, so 96 bits for that, or 12 bytes.

The IP addresses are 32 bits, and you need a source and destination address. So 64bits of IP addressing, or 8 bytes.

12 bytes (MAC) + 8 bytes (IP) = 20 bytes of information. The other 20 bytes are from the TCP stack, and were added when the segment was created. (see above).

20 bytes + 20 bytes = 40 Bytes of NON-DATA addressing and TCP info.

Now, if the MTU is 1500 bytes, then the MSS must be 1500 bytes - 40 bytes, or 1460 bytes.

Any packets larger than the MTU/MSS setting of your provider WILL RESULT IN PACKET FRAGMENTATION. If that occurs, the data is divided up into smaller packets which can traverse the link. Each of these new smaller packets ALSO HAS 40 BYTES of TCP/Addressing info added onto them, as each and every packet MUST have complete addressing info.

So, in summary, your "optimum" MTU/MSS settings depend on your ISP. The MTU can't be larger than your ISP allows, and MSS must be 40 bytes less. In addition, you must account for the LOWEST MTU of all the routers on the particular path through the Internet taken by the pr0n picture down-load you request, otherwise packet fragmentation will occur.

I hope that helps explain it, and didn't get too geeky.

The entry to try in the registry is
HOTKEY-LOCAL-MACHINE/system/currentcontrolset/services/class/net trans/0000 threw 000+ (+ stands for the number) setting MaxMSS forces windows to start hi in the MTU if you graph it without setting this the packets open and close breaking up into smaller packets with MSS set to the higher amount 1460 or lower MTU won't tend to break down as much but it will lower as needed in win98 and SE MSS had a starting point of 536 and built as high as 1460 in win2k its already set to the max this is one of the reasons that there isn't as much to tweak in win2k I'm posting these results at http://microsyspro.com hit the link MaxMSS I'm also posting the link to the tool's I used with this on the site the software is free

08-17-00, 10:24 PM
Thanyou I know I am but what are ? don't worry be happy
Hi You have to add it just like you do with the MaxMTU
If you have added the tweaks from the Speed guide the MaxMTU has been added

Heres where it is supposed to be added or better yet tell me your OS and type of connection and maybe I'll email you the patch

heres where it goes

HOTKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net Trans\0000 and so on
you will have key's 0000 threw 0010 more or less

within though's key's you will have various entry's Rt. click in there and add a new string value called
MaxMSS once thats made double click on that new value and set it to 1460 if your MTU is 1500 if your MTU is 1496 then set the value to 40 less if you have a PPPoE connection go to my web site and go to the bottem of the page click on the link MaxMSS and download the PPPoE patch for mindspring you can always edit it by right clicking on the download and resetting the values to your connection if your not sure write me back and I'll send you the patch for your connection
Good luck and remember to backup your registry
Note: the patch is compatible with win95 win98 win98SE win2000 will not need this patch because its preset from the start as far as I know
I will be making these patch's available on the site so far just the one for mindspring is set
Remember to put the other tweaks in including the system.ini setting for your network card this is important

The standard ethernet packet size is 1496, but many cable companies use a MTU of 1500. In order to not fragment incoming packets when they are redirected by the router, you should be using a MTU of 1496 (And I assume a MSS of 1460?) If you are using DSL, the suggested 1492 is is ok.

In other words, if you are using a NAT router like the Linksys, technically you should not use a MTU larger than 1496. You can test this theory by pinging other computers on your network with something like "ping 192.168.1.102 -f -l 1468"

OK OK I Can't stand it anymore go to
http://www.microsyspro.com You can now download the tweaks for a nominal charge of FREE! One for a MTU of 1500 one for 1496 and for the strange PPPoE which with the MTU of 1492 and MSS of 1420 which seams to work well with the two PPPoE connections I have
Make sure you go to the LINK on the page that say's MaxMSS you can even veiw my D/L speed
Good Luck with these they seam to work for sum and not others and as iv said in the past always backup your registry.
Oh I also included a patch for when you use the old 56k dialup so that you can fall back betweeeeeen the two.......

Thank you for the tip it work great.My pings
were any where between 300 to 400 after reajusting to your settings on all three computers. The pings drop to 30 to 40 on each
computer and the speed increased.I was just about to call the cable company and have them check my lines.You save me the call.

What OS do you have? and do you have the memory buffer set in the system.ini per the speed guide? have you been at your max to start with? In some cases it will not work go to my site email me with the particulars including who your ISP is the other thing is that I had someone try all the files till one of them worked. In some cases MSS with the proper MTU could slow it down and you have to lower the MTU and MSS to get better results this is also why I have the different files at the web site. get me the info maybe we can still get it but it may take some time I'm getting allot of good email on this and a little bad and I don't like the bad so I don't mind working on this if you don't. Unless your happy with your connection
Let me know

But ya know with the amount of activity you would think there would be more of the plus or minus comments here maybe I should have started this with the word un-xxx in it but I don't be-leave in changing a forum
Lets see if the setting is worth having in the tweaks give back some good input this will be the only way to see if this can be a good thing... over all
A setting like this has had some up and downs and the only way to get to the heart of it will be to see how well/bad/unchanged it can be

Cool If your worried about it I now have a way to reverse it out of the registry it will remove all the settings so you will want the original tweak from here for your OS (operating system).

Just like the tweaks here at speed guide. They have to be added goto http://microsyspro.com then the link called speed up your internet it has the MaxMSS/MaxMTU in the tweak. After you download it and unzip it you right click on edit then you can see the actual values of where it is installed in the registry along with the rest of the setting. You may want to read through the speed guide tweaks from the main page here the tweaks here and the ones at microsyspro are very similar except that one has the MSS value in it..

Its a "string" value it can be put in as a DWORD I saw it done that way once. Sorry had to edit.. Im putting up a win2k and a winME in the near future I just got buried with allot of other work as of today. hope to have that answer soon as fare as I know win2k and don't quote me on this it comes preset with a 1460 MSS and the only connection that it has to be adjusted on is a PPPoE ADSL and a connection that has a low ping -f -l and as fare as winME I beleive its close to win98 I think some of the resident members have used the win98 tweaks but don't quote me on that one either till I mess one up
Good luck

This is where I wished I had a win2k machine that I could beat up right now... Im not going to start in on my customers machines until I test it. now as far as I know either will work. The thing is I already know the string value and I really havent had the time to sit down and figure out the DWORD value as of yet. If you enter a string value of 1500 the DWORD value will be different but will give the same results. I'll give you one better I have downloaded the tweak from here and have used it on a win2k machine but I havent even questioned its validity. Because it worked So give me some time to get to that and I hope to soon.
Bottem line im sure the string value will get the results if someone else out there can give a better answer please.
One other thing you can always pull the entry it won't have an effect on restarting
but at least you'll get the final answer, and then maybe you can share your findings
right back here

See what you have started here =). Anyway this is what I have done. I had the MaxMSS as a string value and the MTU as DWORD value.

Since you said both will work I made both MaxMSS and MTU a DWORD value to be more consistent I guess.

By the way my MTU right now is at 1496 and my MaxMSS is at 1468. Sad to say but I am also on a one way cable modem. I used to ping around 250 (Quake 3) but with these settings my pings are now around 200 or so.

I am using Win2K as well. I tried placing a DWORD string in both my TCPIP and adapter settings in the registry. I used the syntax MSS and MTU (rather than MaxMSS and MaxMTU, due to the fact that SGDOTNET does not have 'Max' in front of their tweaks for NT). I actually experienced LOWER speeds with these keys entered than without (from 1430kbps to about 392kbps). Therefore, I would NOT recommend using this in Win2K, at least until danjr or someone else can figure out the correct way to do it in this OS(if there even IS one).

Is anyone else out there having any luck with this MSS tweak running in Win2K?

WhitetrashGod,

Sorry to hear that you are getting poor results. I'm not sure if these settings actually work or not for Win2k since they are not fully tested yet. However I can say that I did see some improvements.

The only tweaks that I entered in my Win2k registry are as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

TcpWindowSize=65535

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\interfaces

MaxMSS=1468
MTU=1496

I left the syntax of MaxMSS and not MSS. You will also notice that I did not enter the other tweaks that are in the registry tweaks that you can download here.

I have entered and experimented with them for about 3 weeks now and so far these registry settings gave me the best results. Or maybe it's just my imagination =). At this point I will take a 200 ping over 250. Good luck

Did the support page help from Microsoft and the other thing is that when I had my cable connection I did run a little higher MSS value due to the weird speed that I was getting from them.. Generally what I'm trying to get at is the rule while not written in stone is that the MSS is usually 40 less then the MTU.
Great feed back

So if you have a mindspring account go get it. You can see the results at the web site it hit 2000 down and a consistant 1900 down

Glad that it helped a bit WhitetrashGOD =).

At least now we know that those settings does something.

DANJR I read all those links from Microsoft that you have posted and it gave me some ideas THANKS!!.

It is true that most people recommend to set your MSS 40 less than your MTU speed but I have also been using DSLReports tweak guides (which recommends a value of 28) and it has worked for me. I tried the value of 40 beforehand and I didn't see any difference. As a matter of fact it actually slowed me down. I noticed it most when browsing the web. Website took a little bit longer to load up. Of course everybody has different setups so for the past weeks it's been trial and error for me =).

Here why don't you guys take a look:

I would definitely recommend reading the MTU part. Let me know if you guys come up with different results. Good luck!!

Like I said the program slowed me down but it gave me the right value I needed to finish it. Now I'm gonna look into the higher MSS value I tryed it before when I was with cable and it may not work on this PPPoE thing I got but I'll try anything.. Well I won't try the UN-*** word or the N***** word
Great who's gonna sort out this thread I have so much here I guess I should start

dannjr
08-25-00, 06:21 PM
Anyone want to reply to this.
Ok here is part of the reason that the programs are not used. Programs are just that, its a program that takes up space. Some of these programs that are out there while they may boost your connection somewhat, they keep you from ever giving you the max. I referred to a program above and everyone has been trying it while the program found a better setting for my connection, it still slowed me down by about 3% or more. If you look at the property's of the program your using right now it will put in some of the same entries that you can get right here.
The bottom line is that yes I'm in here every day to find out if there is anything new out there or to answer questions. I put in the settings and forget them. The files here work the files on my site work. They increase speed they make your connection more reliable and once there in there unless your connection changes you can forget them.
The other thing too, is that programs for speed can load up the registry with things you just don't need. The program that you refer to has about ten or more added entries in your registry. This makes windows work even more, and this can slow you down.
I hope this helped.
NOTE: If you try the files from here or from my site you will have to uninstall the program I know that they will cancel each other out Iv seen the properties for this one and Im positive about that.
Give these a try if you have problems one of us will help I know I'll try
Good Luck
You actually paid $30 for that I couldn’t believe it and then its from Bonzi the products cute but who is Bonzi have you tried looking them up. there really is no help from them.
You can get allot of help here
I don't mean to hit on your program but bonzi ware connects to the web from your computer wouldent it be nice if they gave a true company name and phone # with that security issue

I put this statement on the thread below I think this should help in some of the confusion about MSS and why its there even though there have been differences of opinion the subject was on TTL settings. http://www.speedguide.net/ubb/Forum2/HTML/006557.html
This is what I wrote with a small edit...
Ok lets look at something. The info your looking for is the TTL. I don't know if have defined the other settings. You can correct me if I'm wrong. But the TTL is dependent on all the other settings. You have to get your MTU first this defines the size of MSS and that Defines the DefaultRcvWindow if all thoughs are correct then define the next layer which is the TTL. 64 is good for most apps..
I run 117 I found this to work best for my connection being that its a PPPoE thing with a VPN if your web pages don't come in fast enough then raise the TTL but if the other settings not straight you will have lag.

Philip
08-26-00, 07:23 PM
TTL is a timer and a counter, reduced by at least one with every hop. Increasing TTL will simply cause a packet to live longer before being discarded, while a value that's too low might cause it not to reach distant servers. As long as one is using some sane value that enables packets to reach their destination, generally there is no need to tweak TTL. (One exception is if one has high packet loss, and you must choose whether you want to give a packet more time to live, or less time, in which case it would be retransmitted faster, possibly going another route)

Oh, also, regarding MSS, it is something I had in previous versions of the patches, however it was removed because there is no definite proof from MS that the "MaxMSS" string is a valid Registry entry. Also, Windows calculates MSS automatically based on MTU, so it shouldn't make that much difference with a defined MTU, even if MaxMSS is a valid entry.

Just my .02

dannjr
08-27-00, 02:53 AM
Philip Was up. I like the new server.
I agree with you on TTL in fact here is an other way of looking at it.
TTL stands for Time To Live, the maximum number of seconds that a packet is allowed to be on the Internet before it is destroyed as undeliverable. However, as a practical matter TTL is really the maximum number of hops that will be followed, since TTL is decreased by at least 1 on every hop, and most hops are less than 1 second (usually much less).
The purpose of TTL is to guard against impossible or erroneous routing (e.g., loops where a packet would otherwise go around and around forever); for example, given an intended route from A to E:
A -> B -> C -> D -> C -> D -> C -> D -> C -> D ...
In this case (looping between C and D) the TTL counter would run down to zero and expire, bringing an end to the loop:
32 31 30 29 28 27 26 25 24 23 ... 0
The objective is to have TTL large enough that packets will always reach their destinations over valid routes even with lots of hops, but not so large that excessive resources are wasted when erroneous routing (e.g., looping) is encountered.
In Windows 95 TTL defaults to 32. In almost all cases this is sufficient you have the rest. from 32 to 128 they used 255 as the top end
This is compliments, of: http://cable-dsl.home.att.net/ I did not put the whole article here as it would have confused the whole topic plus the article was fairly
old, very long, and partly inaccurate. if you notice it only refers to windows 95

Now do we agree that Microsoft in all its infinite knowledge has kept us, the users in the dark as far as the registry goes.
Now lets look at something. A person that has a MTU of 1500 has less to gain in the MSS setting with a "clean" connection. We both know there is a registry entry in some of win98 of “DefaultMSS” with a setting of “1460 “ But how is that defined by Microsoft for win98? Im looking into that now
when they made win98, because of the nature of the beast, there was no real need at first with a dialup to tweak it. In fact at comdex that year they pushed it as the first online OS… Some of the Tweak software company's at that time even said that it wouldn’t need there tweak because it didn’t need it. That lasted about a half a year.
As far as MaxMSS in the registry I'm getting more good feed back than bad. As of late. some have said hey I didnt get much in the D/l speed but it seams more stable Let me go dig some more, and if anyone else has info about this or opinion lets here it.
Since we can't find anything at microsoft in the way of a search I made an inquirie about it direct to ms. Plus there are about a billion articals at Novell to go threw I just started there.

Dannjr, thanks for the positive comments about the new server.

Please don't quote John Navas on this, he's been trying to flame us on every tweak he doesn't personally approve. I had an argument with him a couple of years back about the size of the DefaultRcvWindow, that's why he started. Anyway, he's right in many of his recommendations, just that there is no point in flaming speedguide, our recommendations have the potential of giving you better throughput and more control over TCP/IP.

Regarding TTL, I've seen routes longer than 32 hops in the past, and with the speed of current routers you can reach 32 hops within a second or two, meaning that theoretically your packets could be discarded too fast. A bit larger TTL would simply ensure you can reach any destination on the net, also a value that's too large would delay retransmition of data, slowing you down if you're experiencing packet loss. These are about the only purposes our TTL recommendation serves, it is related to the stability of your connection, rather than speed diretly.

I haven't been able to find the exact syntax of the MSS entry in the Registry from MS as well, I hope you have better luck.

Excellent, and perfectly, articulately streamed in. “What you said”.

I didn’t like 99% of what was there. That was the only thing that made sense
on the page. With a little different look on TTL you have no argument with me.
These settings (layers) (Speed guide settings) for TCP/IP have been around for quite some time and they work.

What makes any of us correct, is the fact that the layers work. If they didn’t work we’d be stuck in that “one-dimensional weird, non-multitasking ugly way that he had it”.
Sorry about the quote I really didn’t mean to bring up old hash. I was just looking for a different explanation on TTL .

Now getting back to where this left off before we got on the TTL.

What I was trying to express was the settings in general, and the thread was on “best TTL”. I was trying to express that, before you get your TTL, You should make sure that all your other settings are correct. So at the time I just did a copy and paste from there, and I probably should have given a better explanation and a little more thought on it. Or at least re-do the thing more like below.

Correct me if I'm wrong…..
You have to get your MTU size with a ping (ping -f -l [packetsize] [www.yourisp.com])first. This defines the size of MSS or (-40 of MTU) and that defines the DefaultRcvWindow. In that order, If all of them are set. Then define your TTL. 64 is good for most applications as a start try not to exceed 128.

When in doubt, with any of this, look back at these pages below. http://www.speedguide.net/Cable_modems/cable_registry.shtml http://www.speedguide.net/Cable_modems/cable_registry_advanced.shtml http://www.speedguide.net/Cable_modems/cable_irq.shtml

The Disclaimer???????????
The registry setting “MaxMSS” with a setting of less than of MaxMTU
“may” or “may not” be a valid setting for “Microsoft Windows”. There has been no known bad effect from this setting in fact quite a few, have had good results with it.
Please when working with your registry always make a backup of the thing.

Please Note: Without the people like you at speed guide. that devote about 24 hrs. a day here, there would not be this forum. Nor would there be the help from the hard work that everyone has come to love. Free files, Info and So on. With that thank you everyone at speed guide.

Just trying to help.

You're right, the best way is to find MaxMTU from your ISP first, (adding 28 to the largest non-fragmented packet), then calculate MSS (MTU-40) and the DefaultRcvWindow (MSS * X). TTL of 64 should work well, the exact number is not crucial though. There is one more necessary setting to enable "Large Windows support" if you're using DefaultRcvWindow over 65535 too, I don't think it's enabled by default.

In regards to that last setting that you have said which is required to enable large Rwin support, you are talking about Tcp1323Opts right? I have added this as a Dword value of 3 and when checking my system configuration on http://www.dslreports.com/tweaks it still reports that it is 65535, when in reality I have it set to 372300. I saw in one of the other forums that FrankFuss has gotten this to report correctly by:
"Someone on the dslreports forums answered this. Appling a Windows 98 Patch to Vtcp.386 and setting Tcp1323Opts to a string value ("Tcp1323Opts"="3") did the trick. Now I get the following on the dslreports tweaks test: * Your RWIN is advertised as 356960 (rounded up) Frank"
This was posted in this forum : http://www.speedguide.net/ubb/Forum2/HTML/006597.html
What bothers me, is that I have the most recent patch and am using Tcp1323Opts as dword, and have tried string, but do not see it correctly still. Any ideas why not?

Penguin22,
I almost didn't feal like posting on this. Cause it looked like you wanted Philip to answer. So here it is YES but then again I probably put my foot in it.
Let me ask you something you went to DSL reports ran the test what did it tell you about your PMTU Discovery the only reason I asked this is because on ten restarts and 7 different settings and 2 different caches to clear each time on the server, and ten different IP assignments from the ISP I got a RWIN of 59680,19198,372300,371712 one is correct. Can you guess which one it is. This is the one thing I didn't change the whole time. 371712
PMTU Discovery on every restart of the server
came up 7 out of 10 as off.
You asked a underlying question that I really haden't thought about and that was the validity of the tests at DSLReports.
I usually use them when im in a office and don't feel like putting up my software to test the speed I will use DSLReports for target practice and add about 8% and thats about the speed of that connection + or - the whole thing is "Yes" to the first part. Though mentally done in for the night and have a BIG week ahead Thanks for the second part. Now I know there is no accurate test on line.
Last question. Since you did the update did you put it in manually or with the executable file go back and read again about the update.
Something else you may want to think about is put this question out to everyone in a new thread. I know I don't have all the answers even after being in this business for as many years as I have.
Last thing: I even did the recomendations that DSL gave and slowed the server by 300kbps.
Good nite


-----------------------------------------
I feel another Ouch commin on.
Don't shoot the messenger.

penguin22
08-28-00, 11:36 PM
Yeah, I kindof estimated that the DSLReports was not fully accurate, especially by the fact that he had to round his Large Receive Window value up to be accurate. It really isn't that important anyway, as long as I keep my speeds of 2Mbps... I don't have many people in my town, and have a cable modem.
Maybe you will be able to answer a question that I recently discovered and haven't had time to research yet. My Motorola cable modem works fine with downloading until I upload something. With my new ZyXEL P314 router, it shows that the cable modem is running a 10BaseT Half Duplex line. I knew about the 10baseT... obviously, but are all cable modems half duplex? If not, I think that I will be reconfiguring, if possible, or replacing my current cable modem.
I will try to find out more info. on this if I can between work and college. Btw, as I mentioned to Phil in an email, the MaxMSS setting does seem to boost my speed by a little. And anything for free is better than nothing, so it is staying.

Penguin22,
Thanks for the vote of confidence. It was a weird day as far as support goes and this was a welcomed sign.
As far as the router thing try this there was a report on this about a week back about lowering your MTU just a little and I think if you raise the TTL just a touch.. AS far as I know and I have not looked into it since I had cable the cable modem if they gave you a 3com that would be great.
Oh heres one to try and I almost forgot this is gonna sound stupid but I was told by my then cable company to go into the dialup adapter in the network property's under advanced for IP Packet size and set it to large from default or auto it made a about a nother good difference I could probably tell you how much here but then I gotta dig & that aint happenin right now... let me know what you find I like it when I can file good info
Thanks again
Note I hope I get time for the other OS

Hey Juggernaut
Do me a favor
tell me what was you ping before and now the actuall value, and what your MTU and MSS are
plus the site you connect too. also your OS,other tweaks,and are you useing anyother speed software. Do you seam to connect better with a dialup.
Ping to a server that has allot of users can effect the prefomance so lets see if we can get the cure for gaming. I'm also waiting on a answer from a gaming site about some other info so we may have a answer soon. in the mean time get me your info if you need to, email me off my site if its allot of info

hi may I suggest some settings and see what you guys think of them.

try them and see if you get better results downloads and uploads.

I am using a cable modem (com21) in chicago, Prime cable is the name of the company, which I think the cable modem dept was bought out by @home.?? not to sure but i got great increase with these tweaks below.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans 000?(? this will be a number 0001 or 0002 or 0003... You need to find which one says,
(DriverDesc TCP/IP) this should be in the 000? file. then add this below.

all three are: String Value

MaxMTU 1500
MaxMSS 1460
IPMTU 1492

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP

All are: String Value

DefaultRcvWindow 272600
DefaultTTL 256
MaxConnections 1024
PMTUBlackHoleDetect 0
PMTUDiscovery 1
Sackopts 1
Size/Small/Medium/Large 3
TCP1323Opts 3


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip
This is a: DWORD Value

TCPWindowSize 272600


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters

This is a: DWORD Value

TCPWindowSize 272600

Hey Spiro how you doing
So they finally listened
Well which one of the boy’s gave you this De-on or Antonio….
Or did they email these to you from Frank

Ok getting back to the topic had to edit
ANYONE WITH CABLE WANT TO GIVE IT A TRY WITH THE ABOVE SETTINGS LET ME KNOW THE FINDINGS

Try these three settings Prime is notorious for having the MTU change from one week to the next depending on which admin is their.


1. Delete the entry IPMTU
2. change your DefaultTTL to 128 or 127 worked best with Prime Cable of Chic
3. Try your MaxMSS at 1465 0r 1470
4. I had real good luck with the @home Tweak from speed guide

Add the line to your Network card in the system.ini
Irq**=4096 where ** = the irq of the card
You put this below [386enh]
Get the Irq position form the hardware defaults for windows
Right click on “my computer” click on “properties” hit the tab “Device manager”
Scroll down to “Network adapters” open the properties of the network card
Click on the “Resources tab” look at the “Interrupt Request” that is the Irq
For the nic (network card)
If you have questions about this go to
http://www.speedguide.net/Cable_modems/cable_irq.shtml here at speed guide
There has been controversy about this last one but for almost everyone it works.

I’m currently giving your settings from Prime and I’ll let you know a try just like I do with all the speed software and anything else that people thorough at me. But since you’re the perfect subject and the fact that I had Prime Cable you gotta give these setting a try.
The MaxMTU may be to high but it worked good when I had them. They lost me as a customer when the admin took all the two way customers down for two days. Not to mention the blacks out with the rain storms, and the router from eni the backbone going down 5 or six times when I needed the service the most. I hope there better now.
By the way the Techs had been great easy to talk to gave good info. I even new how many people that were on the node ask Antonio do it before @home takes complete control.
Good luck, and you should get back here more often
Dan

Hey syntax how ya doin.
Philip has a statement here on the BB and he put it so eloquently that it would be a shame to miss “quote” him so I won’t try. But I remember agreeing with him on it. About a week ago.
As far as I know there is a little controversy on the setting I use the setting on all the machines here and have noticed an improvement with file handling and with the proxy.
I also have it running on the win98 proxy server and I noticed that I’m not having to repair IE any more I had real problems with IE blowing up on the server not that I needed the browser on that machine but at times you do need it.
Its like the MaxMSS we all know that windows handles MaxMSS but then when we put in the setting and see the improvement whether it be stability with a small increase in speed or faster d/l of web pages and a 200kbps difference. Dose it work it is for me.
If you put it in your machine and you notice an improvement without clearing your cache
Then it must be working. If you clear your cache and it seams even more stable then it must work.
Like I said before there is allot of things that Microsoft hides from us. When developers go to them, they have to submit a proposal with the way there software works, and a copy of the software with the code. If it fits the scheme for Microsoft, then they develop the new code for the developer as to not tell the developer the whole infrastructure.
Here’s a statement that was released the day win2k came out.
Microsoft releases windows 2000 with 64000 known bugs even there test software failed win2k but I guess it works.
Anyway that’s about the way I feel on the tweak end. If you run it & it works & it don’t slow you down then there something to it..
As long as you backup the important stuff it can always be fixed

One thing I do know allot of people use it. There hasn’t been allot of complaints about it. except for a few that have yet to really prove that it won’t work.
I know the entry has no ill effect, never heard of someone bowing up over it.

I have made the system.ini change and that made a huge difference. I then made my first registry change and set my MTU to 1500 and went to DSLreports to see what the report said. This is what I got
* Results
* Your public IP address is xx.xxx.xx.xx
Hops left before discard (TTL) is 114
TCPopts hex string is 0204020001010402
Max Segment Size is 512
* Your MTU is too small
* Try MTU up to 1500 / 1492(PPPoE)
SACK Permitted (RFC2018)
Ping stability 162 103 102 105 104 100 109 100 98 127
* Quick packet-loss tested ok
DefaultRcvWindow is 65535
Your RWIN limits you @111ms to 4723kbps
Your RWIN limits you @200ms to 2621kbps
* Your RWIN is set ok at 65535
* Problem, Path MTU Discovery is OFF
Max sized data packet from you 552
* Conclusion.. possible problems
* End

According to this my MTU is not set, but I went to the registry and it show my MTU set at 1500 and MAXMSS at 1460. Can any one give me clue at what is going on.

Thanks for your help

Hey Syntax did the system.ini thing help.
Haden't heard back.

Oldman Thats about how I feel right now
I sent you a email on this it's a basic thing about what was posted on page two near the bottem, on DSL Reports

Also I'm finally gonna see just how long it takes me to blow up win2k prof. I deployed it with the sp1 and have already blue screened it. gonna keep this one clear of programs. So I can mess with it thats what happens when you can flop out drives it don't matter how many times you blow up the OS.

Hey dan,

Okay after trying out the system.ini tweak for Win2k for a couple of days. I found no difference on dl/ul or even any difference for that matter.

However for those who are using the Linksys router with Win2k. I found that disabling DHCP and entering your ip address/dns etc on each of your computer in your network helped my ping times.

I have been pinging 180s-190s compared to 250-200 (After applying mtu mss tweaks. Scroll up a bit and you will see my progress report =) ). I also remember Brent saying that this also helps on reducing boot times.

Just to let everybody know that I am on a 1 way cable modem and yes it stinks for gaming but after doing some experimenting I actually lowered my ping times. Either they fixed their lines/server it works for me nonetheless. See you soon!!

I can download files at between 300 - 600 KB/sec. I have gotten over 700KB/sec. What would you be wanting me to post here to show how I got those settings?

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP
DefaultRcvWindow=

09-04-00, 10:54 PM
Hi
Spiro & Nagrom Nnniuq
The basics on this one are to see if the MaxMSS setting in windows 98 helps in a little more speed and stability so all thats really needed is a OS (Operating System) that has been tweaked well and then add the MaxMSS setting to your Registry in some cases it has given a increase as much as 200kbps and lowered ping but this wont happen in all cases it depends on how clean your connection is in most cases where the connection is real bad non of the tweaking in the world will help the same is true of you being on a node that has very few people on it or less than 50 then MaxMSS may not help in speed but could in other parts.
This has also helped in win2k.

Spiro: By the way did you take out the other settings to see what would happen. Like IPMPU
and the TcpWindowSize was way to high between them they slowed it down by 150 and surf slowed down. Ping went up. Let me know.


Thanks Dan

Hi dannjr,

Sorry to bother you I tried some settings and upgraded my service to 1mbps but only get 552 563mbps not much there...

I did some changes and DUH I forgot what settings I had can you please briefly post what changes I should make to MaxMTU MaxMSS and DefaultRcvWindow.
If you remember what settings you ahd working best for you when you had prime cable.

PS I did remove the IPMTU and tried talking to the guys at prime but niether one gave out any info. No idea why but they clamed up. http://www.speedguide.net/ubb/wink.gif

Thanks again, sorry I don't get around to much on the forums to help out but I am eorking 9-9 6days a week so I try but my mind just doesn't function to well after 12 hrs at work. http://www.speedguide.net/ubb/smile.gif

I do though appreciate all your help.

is there a dsl company that you think might give me better than 600 or 700mbps... anything better than Prime Cable would be great....

Hi there again,

Hey Check this out guys... I just had a guy come out to my house and do a check on my cable line cause I was getting garbage for speed. I just deleted all settings in the regedit: MaxMTU deleted, Max MSS deleted, DefaultRcvWindow Deleted, DefaultTTL deleted,
SacOpt deleted, IPMTUdiscovery deleted and some other ones I can tell you all if you like?
But know I am getting 780 to 836 was my highest speed??? Mind you at 3:30pm chicago time this I would consider rush hour on the net.

Now the test was done on my cable companies speed test, but it did give me a BIG difference than before... I posted the speeds above in another message earlier. almost 300 difference. WOW I am amazed.

How I came to this conclusion to delete the settings?? The guy did a test at the main NOD 6 city blocks away on his laptop, and he was getting 648 686 701 724 (right around there) after we went back to my house and did it with his lap top, it was about the same speed. then I tried my computer and thought mabe I would get a better response.. Still no luck. So I asked the guy If I can get into his reg system and looked at his configuration and he had no settings what so ever??? I thought this is weird?? no tweaks at all?? So I deleted all my tweaks and got an amazing 300kbps more.
He had a pent 166mhz chip and win95 on his laptop.

PSS. I am running win98 SE on a pentIII 550 128 MB sdram with a Voodoo3 3500 tv AGP 16mb video card. I have no Idea what just happened but it is rocking, from what I use to get... I can't say if it will help everyone out but no need for tweaks on my system... they all slowed me down 300kbps... So if you want to try it out and see what happen's just don't be mad at me if it don't work for you.

PSS. I am paying for 1mbps and have a COM21 modem with Prime Cable.

http://www.speedguide.net/ubb/smile.gif WOW.

From what I see its a start but why do you have the IPMTU set to 0.
Have you D/L the tweaks from here or from me to see the settings for Win98 or the other OS.
What is the speed your paying for? if its more than 500 you can probably improve it.
So get me this info and lets see if this can be improved.

From what I'm seeing in your tweak set is that you really need to read the pages in the speedguide this one should have the biggest effect and take out the IPMTU entry you really don't need it.

read threw this page and the advanced page

Yes I have already done that. I have done quite extensive work with windows registry editing on NT and 9x. I set the settings this way because this is the way I wanted them. I will keep tweaking them to see if I can get better speeds, but as far as I can see (from what I have read here) no one is getting even close to my download rates! Please correct me if I'm wrong. I got a bunch of email as soon as I posted this of people wanting to know how I got this fast and that they could only get about 100KB/sec. As I said I almost never drop below 500KB/sec. I do pay for 1 - 1.5 MB/sec though and my goal is to get my downloads that fast also. This is a great website though and I do use the info supplied here.
