dopo svariati tentativi per capire come mai quando setto MTU a 1500 poi resta a 1480 intanto mi hanno messo la 4mega...sia lodato dio fivendra...però non riesco a settare bene questi parametri come mi avevi detto di fare...
ti posto questi che sono aggiornati...sperando in una tua risposta ti ringrazio anticipatamente
TCP options string = 020405a00103030101010402
MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1440
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 126720
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled Receive Window = 63360
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
63360 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 5068.8 kbps (633.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 2027.52 kbps (253.44 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
