SpeedGuide.net TCP/IP Analyzer:
MTU = 1476
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 = 1436
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 5840
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 5840

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
505472 (MSS x 44 * scale factor of 8)
252736 (MSS x 44 * scale factor of 4)
126368 (MSS x 44 * scale factor of 2)
63184 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 233.6 kbps (29.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 93.44 kbps (11.68 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops

TTL value is ok.
Timestamps (RFC1323) =

Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000



Se qualcuno potesse perdere 5 minuti a guardare questi dati e darmi un consiglio, sarebbe cosa gradita...
Ciao a tutti!
