ho letto il post di Fivendra su come settare l'adsl al meglio, sto provando a farlo (ho un modem USB) ma come posso cambiare pppoe in pppoa? poi come faccio a settare il giusto valore di RWIN se non conosco il giusto valore di MSS?
TCP options string = 020405a00103030301010402
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) = 506880
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled Receive Window = 63360
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 20275.2 kbps (2534.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8110.08 kbps (1013.76 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
