TCP options string = 020405b40103030001010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default TCP Receive Window (RWIN) = 64240
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 64240
RWIN is a multiple of MSS
Other RWIN values 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) <-- current value
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your TCP Window limits you to: 1027.84 kbps (128.48 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 (0)
MTU ed RWIN sono settati bene?
Grazie
