TCP options string = 0204058c0103030201010402
MTU = 1460
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1420
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:
522560 (MSS x 46 * scale factor of 8)
261280 (MSS x 46 * scale factor of 4)
130640 (MSS x 46 * scale factor of 2)
65320 (MSS x 46)
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 = 121 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
questo e il risultato del famoso test...ho letto i vostri post a riguardo...e mi sono detto..se ho capito qual cosa quell RWIN) = 255552 e la causa dei miei download che saltano da 60/70 a 10 4 kbs
ho deciso di cambioarlo ma sia con il programma drtcp sia con mtuspeed4 salvo i cambiamenti...e dicono entrambe ok...riavvio..rifaccioil test..e sempre quel maledetto 255552
tutto questo su windows xp...consigli?
