tweaks?

I'd like some feedback on these settings, do they look ok? Thanks.

TCP options string = 020405b40103030301010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.
Default Receive Window (RWIN) = 510296
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 63787
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

Your RcvWindow limits you to: 8164.736 kbps (1020.592 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 117 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000

No I believe your RWIN number is to big and is not a muliple of MSS, what does it matter if it says you are downloading fast when you have packet loss you are missing some of the download

It's a remnant of cablenut 3.5 or 3.65, I can't remember. I saw that it isn't a multiple. Thanks Lobo, anyone else please chime in.

Lobo · Post by **Lobo** » Mon Mar 26, 2001 3:05 pm

Do this:Cablenuts new version:
First go to www.cablenut.com , click on software at top of page
Download 4.0 (Only users of WIN 95 and WIN ME need 4xx to 4.02 too along with 4.0 )
His patch will uninstall previous patchs
Install 4.0 (If running WIN 95 or WIN ME Install 4xx to 4.02 too)
(NOTE) If you are running WIN 98 or SE, you need to download and install Vtcp386 for patch for 4.0 to work.
Then on desktop click on cablenut 4.0
Click on ccs files
then click on cable, PPPoE or DSL
Select either normal cable or fast cable (See instructions)
this will enter settings
click on save to registry at bottom, reboot or it will not work.

If you decide to remove Cablenut's patch, use uninstaller in Cablenut 4.0 folder on desktop. This will take you back to Windows default.
Retest and repost so I can see if patch is in Copy all this by highlighting everything in box with mouse
(you may have to make box smaller. To copy contents of box, highlight, then hit Ctrl & c, on your keyboard, when you return to Speedguide in reply box, with cursor blinking, hit Ctrl & v, this will copy contents in box so I may look at it. Thank you.
Click on Cablenut 4.0 on desktop, RIGHT click on adjuster and select short cut to desktop, the same with Reboot.

CHECK BACK FOR UPDATES
Would not be bad idea to bookmark this page so you can return for updates or reading.

rebooting box now, will post settings in just a minute after applying cnut 4. I like my new abbrev. for that, lol!

Yea thats kewl, what size CPU do you have

Running a 650 Mhz Coppermine, with 256K SDRAM, and 30 gig hard drive. Running @Homeless cable modem. Using Win98SE till XP comes out.

Here's my results after applying patch, RWIN seems really low (used hi speed cable)

know its not the most accurate, but after applying the 4.0 patch, here was what i got from dslr:

Finish.

(Couldn't tell much difference)!

OK, patch is in, all looks good, if you raise RWIN, raise it to 385440 and no higher,
leave globalmax box blank, all other blank boxes on adjuster just mean default settings are being used, you need to redownload faster loading of web pages from this site:
Do this:
Go to main page this site, select patches on left side of page,
go down until you see Web Patch - faster loading of Web Pages
Select the one for your OS, and download.
To install, click on what you just downloaded-unzip to program files, go there and click on it, click yes and reboot, your done.

Figure you mean the web speed patch from speedguide, there was no link! Will try the adjusted RWIN too. Report back shortly. Thanks!

Lobo · Post by **Lobo** » Mon Mar 26, 2001 3:39 pm

This is what you want and the link:SpeedGuide Web Patch

steve · Post by **steve** » Mon Mar 26, 2001 3:40 pm

Restarting my main box (thank god for home networks). Applied web speed patch and raised RWIN to your suggested value. Will post results shortly. Thanks for all your help, Lobo!

How do do speed test
1. The best time is early in the morning (3 AM - 6 AM)
2. Make sure defrag has been run so no files are fragmented
3. Delete Temp internet files, not while testing, but after each test. IE browser, click tools, internet options, click on delete files and no this will not harm system, just get rid of temp files
4. Go to a fast server such as www.happypuppy.com and click on 10 demos, select a LARGE file to download (not all of it , just most of it, before you click cancel) this will show you how fast you are downloading, it's not going to be quick except except early in morning when not many people on net. I recommend you go to www.analogX.com and download Net State live, run this while downloading as it will give you avg of your download speed, really all you need on Net Stat is incoming data, incoming totals and Local machine, right click on Net Stat anywhere, stactics and check these 3 items, the rest need not be checked unless you want them, all you care about is average.
Put system defrag in scheduled tasks to run everyday.
5. Probably the most important, nothing can be running during test, no firewalls, no virus stuff, no ICQ, no AIM (some of you may have to go into BIOS to disable virus scanner, nothing running except Net Stat live
Scheduled tasks will run disk defrag, 98 & SE in Taskbar, WIN ME in control panel
The people who want speed surfing or doing whatever must close all other programs.
(NOTE: at present time www.AOL.com seems to be fastest download site, at bottom download aol 6.0)
Or if you wish you may go to www.testmyspeed.com and do one of the online tests, these vary to much for me but you may like them. Another one is at www.dslreports.com/tools

To what it says above an download from www.aol.com

steve · Post by **steve** » Mon Mar 26, 2001 3:57 pm

it started d/l at around 190K, then dropped slowly to 105 to 110K. Didn't maintain a steady speed.

Lobo · Post by **Lobo** » Mon Mar 26, 2001 3:58 pm

Go back to what it was 204400

steve · Post by **steve** » Mon Mar 26, 2001 4:01 pm

ok, just dl'd from happypuppy at 165-170K. Will go back to 204440.

steve · Post by **steve** » Mon Mar 26, 2001 4:18 pm

got much higher download speeds from happypuppy and aol using 204440! :-))))))))

Will be faster earlier and if you have anything besides volume and display next to your time in taskbar, exit from it, it's running you just don't know it

steve · Post by **steve** » Mon Mar 26, 2001 4:35 pm

Thanks again for the help, I'll keep checking back for more updates. I slacked off for a while!
