Hello,

Just want to have someone look at my tweak info and let me know if I am fully optimized.

Thanks,

TCP options string = 020405b40103030201010402

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) = 256960
RWIN Scaling (RFC1323) = 2 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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 52 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Feel free to try the tweaks below in my sig. Go Download Cablenut At http://www.broadbandnuts.com . Insert 64240, 32120, or 22000 as your Rwin. You can do that by opening the adjuster and find where the 256960 is and replace that number with one of the top numbers. Reboot after each insert and do a speedtest to see which Rwin is better for you.

If he installs Cablenut where is 256960 going to be at since Cablenut uninstalls all prior patches

Using DrTCP, I changed RWIN to all three suggested (64240, 32120, and 22000). I got the best D/L speeds at 64240!

Thanks!

Using DR TCP see if these RWIN's are any faster, try: 192720, 204400, 208720 or 22484:)
