TCP options string = 020405ac0103030001010402
MTU = 1492
MTU seems to be optimized for PPPoE... If you are not on a PPPoE connection, consider increasing your MTU to 1500 for optimal throughput.
MSS = 1452
Maximum useful data in each packet = 1452, which is equal to MSS.
MSS is optimized for PPPoE. If you are not on a PPPoE connection, consider increasing your MTU value.
Default Receive Window (RWIN) = 17424
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17424
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 696.96 kbps (87.12 KBytes/s) @ 200ms
Your RcvWindow limits you to: 278.784 kbps (34.848 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 38 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
2761 connections tested since 03.10.2001.
cablenut dose'nt work and i can't find defaultrcvwindow in registry .
i was able to change rwin before i updated driver on modem.
after update i could'nt find default rwin value in registry it vanished.
is there a patch to fix this? and what rwin size do you recommend to get optimal performance?
os = win me.
