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) = 511104
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 63888
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
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: 20444.16 kbps (2555.52 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8177.664 kbps (1022.208 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 55 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Speakeasy speed tests say 544 down and 134 up

My caps are suppose to be 768/128....any Ideas?

Your RWIN is way too high for those caps. Try 31944, 43560 or 63888.:) ;)

What about if my caps are at 1.5mbps download, what RWIN should I use then?

[Rainbow]

Used all 3 of the rwin's you posted and tested from 3 different locations....all the speeds were almost Identical...544/136....542/138........544/135 respectively. Uploads hitting caps but downloads not? Beginning to wonder if I dont have 512/128 which verizon no longer offers but maybe Im granfathered in since I've had it for 2 years???
