MTU = 1472
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1432
Maximum useful data in each packet = 1432, which equals MSS.
Default TCP Receive Window (RWIN) = 128000
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled TCP Receive Window = 64000
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values 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 (Note this is not a speed test):
Your TCP Window limits you to: 5120 kbps (640 KBytes/s) @ 200ms
Your TCP Window limits you to: 2048 kbps (256 KBytes/s) @ 500ms
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 (0)

Da linux senza download manager scarico a 480kb/s...da windows senza dm a 250...con download manager riesco a raggiungere i 480lo stesso....per questo penso sia un problema di questi parametri.
Mi potete dire in base ai dati che ho fornito quale mtu devo inserire in drtcp? ho PPPoE
grazie in anticipo.
