Dont worry about your computer, tweaking doesnt have a requirement! :)


Run the TCP/IP analyzer and post the results here.

HalfLifer, Here are my results. i have the win2000 patches installed and the fast cable modem tweak installed using cablenuts.

TCP options string = 020405b401010402

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) = 64240
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 64240
RWIN is 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)

bandwidth * delay product:
Your RcvWindow limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 37 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Ok, are you familiar with adjusting your RWIN?

Kind of. it's in tcp/ip in the registry right?

Open up Cablenut, and find DefaultReceiveWindow, GlobalMaxTcpWindowSize, and TCPWindowSize, and set those to 513920.

On AIM, Polokid54.

Reboot after you changed those settings?
