Need Perfect/Usable RWIN
Posted: Sun Apr 07, 2002 3:07 am
Hello, I'm new to the board but I've been visiting SpeedGuide for a while now. My company (Earthlink) had sent me here in the first place. I have been having problems with my registry settings, I think I have adjusted everything but I need some help with my RWIN. Earthlink assures me that the server is very close to me and if I am having any problems it is on my end....
I am using: Windows ME and RASPPPOE | Earthlink ADSL
TCP options string = 020405ac0103030201010402
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) = 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:
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: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 118 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
Please help me out and give me any suggestions that should help my connection.
