Ho ADSL Tiscali senza canone a 256 anche se mi hanno detto che a Marzo raddoppiava....ma sinceramente non so se già quetso è evvenuto per me!

TCP options string = 020405980103030001010402
MTU = 1472
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1432
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 65392
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65392

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
504064 (MSS x 44 * scale factor of 8)
252032 (MSS x 44 * scale factor of 4)
126016 (MSS x 44 * scale factor of 2)
63008 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 2615.68 kbps (326.96 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1046.272 kbps (130.784 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 58 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
