TCP options string = 020405ac0103030101010402

MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS = 1452
Maximum useful data in each packet = 1452, which equals MSS.
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 75504
RWIN Scaling (RFC1323) = 1 bits
Unscaled Receive Window = 37752
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 3020.16 kbps (377.52 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1208.064 kbps (151.008 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

qualcuno che possiede alice mega potrebbe darmi qualche suggerimento su quale valore RWIN adottare, in quanto con quello che ho, la mia velocità di download non è mai costante.
thx
