How to change your Unscaled Receive Window in win2k in the registry
I got this
TCP options string = 020405b40103030301010402
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) = 292000
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 36500
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: 11680 kbps (1460 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4672 kbps (584 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
ok, i was wonding how to change my recieve window from 36500 to something else, if that would increase my speed. will it help? and if not, i would still like to know how to change it.
and if there is anything else that needs changing, tell me pls.
