TCP options string = 0204059801010402
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) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.
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 (Note this is not a speed test):

Your TCP Window limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your TCP Window limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 118 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
Digli di provare a portare MTU a 1500 con drtcp (da settare anche nel router all'occorrenza) e di portare sempre con drtcp RWIN a 256960.
