Hi! Need some advice.
Used Speedguide tweaks to try to increase speed. Speed guide tweaks used to work for my com, Used to get higher values for rcv window limits. But after reinstall of x.p, the rcv values seem to be stuck at a low value even after tweaks from speedguide at the values shown below.
Only the rwin scaling(rfc1323) is changed from 0 to 2. Even when at windows xp default. the values are as below. Any advisw?
Using motorola sb4100 usb cable modem.
------------------------------------------------------------------------------------
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 1460
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 365
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)
64240 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 58.4 kbps (7.3 KBytes/s) @ 200ms
Your RcvWindow limits you to: 23.36 kbps (2.92 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
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
