TCP properties for IP = xx.xx.x.x.x.x.x.x.x.x(bgp01016483bgs.rosvle01.mi.comcast.net)
Note: Read the FAQ if the above is not your IP address.
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461)
TCP options string = 020405b40103030001010402
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) = 32767
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 32767
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)
bandwidth * delay product:
Your RcvWindow limits you to: 1310.68 kbps (163.835 KBytes/s) @ 200ms
Your RcvWindow limits you to: 524.272 kbps (65.534 KBytes/s) @ 500ms
Download the TCPOptimizer in my sig and choose cable modem and optimal settings then reboot to take effect. Also follow the tips in my link "My Tips", you might also try custom RWIN's of 64240, 96360 or 128480 (if you set RWIN to 64240 uncheck both boxes in Tcp1323 Options section).
