Hi,i'm a new user and i would like to know if it could be possible to make change to have a better performance or if i have to stay that way:

TCP options string = 0204058601010402

MTU = 1454
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1414
Maximum useful data in each packet = 1414, which is equal to MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
65044 (MSS x 46)

bandwidth * delay product:
Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 47 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

, you have 2 problems, MTU and RWIN, what OS are you on and how big is CPU:) :) RAM, how much:)

First:



Click on help page below in signature and follow directions exactly, please leave your OS and system specs if you have not done so.Also if you have Cablenuts adjuster installed I need to know that. On 2nd page of help page at bottom are some Tips and how to do speed test. Thank you and good luck, will fix MTU later
:)

I still need OS (Operating System) very important, leave me that before you fix MTU, WIN 95/98/SE/ME WIN 2000 WIN XP ??????








To fix MTU go to help page below in signature, the middle of first page it says DSL, click on that, you have to change the number in (MaxFrameSize), then REBOOT as soon as you change, this should change it in registry in the INF (installation file) that came with your DSL PPPoE is MTU of 1492, ADSL and Regular DSL MTU is 1500. Good luck. Directions on help page. Good luck:) :) :)

That i said i'm running with: P3 800
512 mb Ram
ASUS CUSL2-C Motherboard
Windows 98SE
ISP = DSL Bell Sympatico High Speed
Cablenuts not installed

You need Vtcp386 Fix patch for sure: Unless you already got it, please take analyzer test


Go to Speedguides tweaks here-below in my signature. Once on patch page you need Vtcp386 Fix
patch for your OS (Make sure you get right one) Download and install, reboot, and retest and do this please so I can make sure patch is in:
At top where it says edit click and select, Select all,
Then go back to same edit button at top, click and select copy.
Come back to Speedguide, same thread you were on, in post reply box, with cursor blinking at begining of box go to top, edit, click, select paste, click, this will put information in box. Thank you.:)

Are you going to try an fix MTU now, PPPoE is 1492, regular DSL is 1500
PPPoE you have to log in with name and password everytime you go on net:)

But,the thing i would like to know if it will increase the speed on the net or i won't be able to feel a big difference.

You see MTU and RWIN work together, yes it will increase speed when we are done, are you on PPPoE as that is the patch you downloaded:



PPPoE you have to log on with name and password.
PPPoE ( Point-to-Point Protocol over Ethernet ) is a method for building PPP sessions and encapsulating packets, as described in RFC2516. Although it is not a standard, PPPoE is already being used by a number of DSL providers. It requires either routers that have built-in PPPoE support, or PPPoE software to "dial up" and establish the session.

Since you did not answer I will assume you are on PPPoE as that is patch you downloaded, write down RWIN *Default Rvc Window) so you will have it and if you get MTU to 1492, call ISP, maybe they can talk you through it, try this to:



For Win 9x bring up Cablenuts adjuster inside icon on desktop in box that says Cablenut,click on adjuster, in box that says DefaultRvcWindow take out number that is in there and put in one of these, 1 at a time, try:31944, 63888




At bottom click save to registry, and REBOOT each time you change value in adjuster or it will not work. On help page below in signature, 2nd page, at bottom are Tips 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. Another fast download site is ftp.lucasarts.com
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.
