Grazie
Ho letto il tuo vecchio post.
Questa è l'analisi della mia connessione:

TCP options string = 020405ac01010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 4288
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 4288

For optimum performance, consider changing RWIN to 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: 171.52 kbps (21.44 KBytes/s) @ 200ms
Your RcvWindow limits you to: 68.608 kbps (8.576 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 120 hops

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



Mi daresti una mano a configurare Dr.TCP???

Grazie
