Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461)

TCP options string = 020405a001010402

MTU = 1480
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1440
Maximum useful data in each packet = 1440, which is equal to MSS.

Default Receive Window (RWIN) = 29200
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 29200
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)

well i have a 1 gig thunderbird amd chip and 512 sdram

[sentra8777]

well i ran this program called sandra and it said my nic card pci latency is to high it may hog the bus for to long

Well download SG Optimizer as it has a latency test in it: Download SG Optimizer to your desktop, select connection type at top, select optimal settings at bottom, click on apply changes at very bottom, Select adapter you are using and REBOOT
If you wish to enter custom TCP recieve window select custom settings at bottom, enter what you wish, click on apply changes at bottom and REBOOT.
If using Cablenuts adjuster too, you must first bring up adjuster, click on delete Cablenut Tweaks at bottom and reboot, then download and install optimizer.


Optimizer in my signature:)

Do your speed tests here after you turn off all running programs http://www.speakeasy.net/main.php?page=sup_pops , select site nearest to you, turn everything off thats running, Check Tasbar, 1 browser, clear cache


Even though it is not the nearest the Dallas test is pretty quick


BEFORE SPEEDTEST
1.) Make sure defrag has been run, defragmented files slow you down.
2. At top of IE, click on Tools, internet options, click on delete files and click on offline files (It's safe), click on clear history, yes
3.) Go to Start button, programs, accessories, system tools, disk cleanup, Click OK (Safe)
4.) Run scandisk (Short version)
5.) Scandisk on XP?
Click on My Computer, select Drive that XP is on, RIGHT click on BLANK place, select properties, then tools at top tab, click check now, check box automattically fix system errors, click start,
then test. Turn all running programs off. Reboot computer so you have all your RAM

Latency test will look something like this, you can take out some of the real high servers and put in what you wish, it is also peak time, hockey time, Miller time:

Oh it not net latency its pci latency i guess the settings are to high somewere in the bios. I just dont know were to go to change it. I have a real tech or realtek i think thats how its spelled. Are those good net cards or should i just go and buy a 3 com.

Try Tcp Recieve Window of 31680 or 63360:)


Is this a PPPoE connection:



What is PPPoE- DSL users only, MTU 1492- PPPoE you have to log on

with name and password. (Not log on to Windows, but to get on net)
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.


MTU in XP is 1480
