TCP options string = 020405b40103030101010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.
Default Receive Window (RWIN) = 123496
RWIN Scaling (RFC1323) = 1 bits
Unscaled Receive Window = 61748
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 4939.84 kbps (617.48 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1975.936 kbps (246.992 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
