1. Your ISP, their caps and type of connection.

Bell Sympatico HSE DSL (Caps: 960/120)

2. Your maximum anticipated latency.

311.666ms

3. RWIN that you found with the formula.

= 960*311.7= 37404
= 37404/1460= 25.619
= 26*1460= 37960

Perfect RWIN =37960

4. Did your speed improve?
I did 5 tests at speakeasy.net and the results were:

1. 798/103
2. 764/102
3. 798/103
4. 792/103
5. 789/102

Avg is about 788.2/102.6

Results indicate that my speeds haven't really changed much, however, they do seem consistent.

Hope that helps in your research

can someone tell me how to save my tracert results. i tried the stuff on dslnuts.com but when i put in the cmd lines all i get in my documents is "pluginxxxxxx.trace" or something like that. can anyone help?

put it in just like this ( tracert dslnuts.com >C:\tracert.txt ) then be patient it took a bit I thought something was wrong then itl get done mine went c:\documents and settings etc. but the file wont be in documents ittl be under C:\ and it will be tracert.txt I tried 2 times cause i wasn't patient enough but I waited and woomp there it was just like i posted

Mopwr2u1 · Post by **Mopwr2u1** » Tue Apr 29, 2003 7:10 pm

actually this would be to find your latency is this under a full download from newaol or the other one??
if so ya take the largest # then ya do it 4 more times and take the largest # then when ya got 5 complete ya take the largest and smallest from them and ignore them then ya average out the other 3 (ontha one ya did the largest is 181 ms) on line 17
sorry it took me so long I had to go somewhere real quick but ill be here the rest of the night

hopefully il go back next week
Sorry to degress Ill be more than happy to help ya polishmafia4u I knew jack squat when I first joined here Im no STEELE but Im learning!! that dude is just need I say more !!!

polishmafia4u · Post by **polishmafia4u** » Tue Apr 29, 2003 8:32 pm

1) Cox HSI, 3000/256, cable connection
2)Max anticipated latency =155.3
3)Rwin=58400
4)Basically speed stayed the same(about 2500-3000) i know not to expect more from a 3000 cap but im just trying to see if i can get them to stablize a little more. sometiems ill get 2800 or so and others like once today i got 4133, so it all in good fun

thanks Mop. i finnally understand how to do it. thanks for the help. im starting to learn some too but not as much as steele

. oh yeah and i used the OOL download to check my latency. thanks again, peace

joshjerm89 · Post by **joshjerm89** » Tue Apr 29, 2003 10:24 pm

didnt work for me( the steele settings), maybe i didnt calc my ping right. my speeds wetn down when i did ur settings. i got comcast in pa, does anyone no wut my ping should be? should i call the technician. cuz i dont feel like doing the test. also isnt lower ping better? like for gaming on the internet, i always have lower latency than others and i have it fast. others who have high latency say their gaming is slow. also i got 1500/256 cable comcast.

oh um when i did steeles tweak for upload,( the default send window) it became unstable. before on pcpitstop.com i would get steady test speeds of 238-242 for upload. with the change u gave me. my speeds would go down to 140 and go up to 280 for upload. very unstable.
is there a more stable settings, but faster than the windows default?

Vic Mackey · Post by **Vic Mackey** » Tue Apr 29, 2003 10:59 pm

ok i wanna make sure im doing this right. so my average was 509. so when i put it into the formula i got an end result of 125560. does that sound right to you? now steele when i was downloading the file and did the tracert my ping times were alot higher then normal. is that supposed to happen? to get an average of 509 i had some in the 100-250+ range while downloading. but i ran tracert again after i stopped download and my ping times went back down to 10-30ms. was that supposed to happen? oh and steele if my upload cap is 384 would would i put in for DefaultSendWindow?

P.S. my cap is 2000/384

mnosteele52 · Post by **mnosteele52** » Tue Apr 29, 2003 11:08 pm

Hey Vic, let's use 500ms for your max (that is a bit high, but it is supposed to rise). So here are the settings you should use:

DefaultReceiveWindow = 230400
DefaultSendWindow = 49152
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit = 64000
MediumBufferSize = 150400
PriorityBoost = 0
SmallBufferSize = 12800
TransmitWorker = 32
FastSendDatagramThreshold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 125560
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAcks = 3
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 125560
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 90

Was there only one server or many with 500ms?

It seems some people forget to say thanks for all the work ya go through Hopefully what i did and put on the thread helped ya out with what you were originally looking for I am very happy with my speed just seems funny how the speed test was higher on the lower Rwin and the big file transfer did a hair better on the higher Rwin
and Again thanks for the time ya put into these threads

chpalmer · Post by **chpalmer** » Tue Apr 29, 2003 11:53 pm

1. Charter 768/128

2. I averaged about 125ms(8pm) but figured for 200ms

3. 18980

4. Oh Yea!

Ive always kept the rwin between 32k and 64k.
Ive never been over my caps before, usually 93-95 Kbytes

after change 98 KBPS average, 8:30- 8:45pm!

guess I should of listened to the rwin calculator before!

Sorry Vic it's supposed to be 256000.

I want to say thanks to everyone for their input on this, it's not really anything new, it's actually the "proper" way of finding the best RWIN for your connection and it seems to be the best way from what I have found out.

i have cox hsi with caps of 3000/256. the rwin i used was 58400 for a 155.3 avg latency. this is for win xp pro

blebs · Post by **blebs** » Fri May 02, 2003 7:32 am

I finally got around to doing this. Do I get a paid vacation now?

1. Your ISP, their caps and type of connection.
North East Ohio Road Runner 2000/384 Cable

2. Your maximum anticipated latency.
100ms (103.4)

3. RWIN that you found with the formula.
26280

4. Did your speed improve?
No slower, No faster. It's about the same. I did have 256960 and scaling enabled which is what I'm comparing against.

mnosteele52 · Post by **mnosteele52** » Fri May 02, 2003 10:56 am

Thanks for the input blebbs

, two questions though.... did your speed tests from distant servers improve and are web pages loading faster?

What I'm seeing is that close servers your speed may or may not improve but with distant servers there is a noticeable improvement. So overall one's connection is much more stable.

Right. I didn't get faster... but things got a lot more stable.

polishmafia4u · Post by **polishmafia4u** » Fri May 02, 2003 5:34 pm

another update. with the rwin that i found, things are not as stable(although the last 2 days have been pretty good so its hard to say just yet) but when i ran the speed test i got 4800 kbps. i thought it was a joke so i decided to test it...only to find i was downloading at 550-600 kBps! very nice considering my caps are 3000. although, upload is upsetting, only getting a very consistest about 130 compared to my 256 cap...but if my down speeds are this fast, im not sure i wanna mess the good stuff up just yet...

edit: huh, i guess maybe it is more stable. this is the first time ive reached and stayed at my 3000 cap on the other side of the US(NY). most of the test on the east coase were consist at about 2800-3000 or so. considering i am in CA this is pretty good IMO.

I didn't see anything noticeable. The numbers stayed about the same. Now if I had to judge by disk thrashing, I'd say it was more stable, but by the numbers I couldn't tell. Pages always load fast on this machine. I really didn't notice a difference there either. I may have to try again on another day. I'm routed through some of the worst AOL (ATDN) routers from my location and checking on packet loss, it was substantial going through the network no matter what settings I used.

ftp://ftp1.optonline.net/pub/test64

While the file is downloading you need to run a tracert to a few websites of your choice. Write down the highest number you get with every tracert. Do this test about 5 times and drop the highest latency you get and the lowest latency you get and average the other 3. This number will be your maximum anticipated latency.

I've 2 questions:

1- I need to complete download the file to get the maximum anticipated latency?

2- I'm a little confused about the maximum anticipated lantency. I'll ping 5 websites , right? I'll get the highest, lowest and the average latency in every ping? Hmm? Or I'll get the highest number in the 5 pings and then I'll choose the highest number?

Thanks in advance..
