cel 433 256-ram DSL PPPoE W-98

TCP options string = 020405ac0103030301010402

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) = 524176
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 65522
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: 20967.04 kbps (2620.88 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8386.816 kbps (1048.352 KBytes/s) @ 500ms

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

try the rwin's recommended by the analyzer... I use 671712.. it works best for me.. I've tried almost all of them..

p.s. which pppoe client do you use?

trial and error, which ever rwin you think works well with your computer
