I am fairly new to all this so i'm not sure if what i did was correct or optimal. i would appreciate it very much if someone could tell me if this is right... but would love any suggestions on making it better. i dont want it to be on the ok side. i want to get as much juice as possible. THANKS FOR ANY HELP!
This is what i have now... showing. by the way... i'm on a hub, which might be why my MTU is not 1500... but it was showing at 1496 before i used CmtuTool and entered in 1500. Now it's less. ugh. also... how the do i get the icq under xp. isn't the nic suppose to have to icq #'s assigned to it?
TCP options string = 0204059c0103030201010402
MTU = 1476
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1436
Maximum useful data in each packet = 1436, which is equal to MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
505472 (MSS x 44 * scale factor of 8)
252736 (MSS x 44 * scale factor of 4)
126368 (MSS x 44 * scale factor of 2)
63184 (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) = OFF
Time to live left = 48 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
