TCP options string = 020405500103030201010402 
MTU = 1400 
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. 
MSS = 1360
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
 
Default Receive Window (RWIN) = 255552 
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 63888 

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS: 
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
 65280 (MSS x 48)  
bandwidth * delay product:

Your RcvWindow limits you to: 10222.08 kbps (1277.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4088.832 kbps (511.104 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
