this is DSL line using Speedstream modem.
TCP options string = 0204058601010402
MTU = 1454
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1414
Maximum useful data in each packet = 1414, 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) = 30932
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 30932
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
65044 (MSS x 46)
bandwidth * delay product:
Your RcvWindow limits you to: 1237.28 kbps (154.66 KBytes/s) @ 200ms
Your RcvWindow limits you to: 494.912 kbps (61.864 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 48 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
