Vanno bene questi parametri?

Per chi ne sa, questi parametri sono giusti per una 4 mega?

MTU = 1460 MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1420 MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 261360
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 65340

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
522560 (MSS x 46 * scale factor of 8)
261280 (MSS x 46 * scale factor of 4)
130640 (MSS x 46 * scale factor of 2)
65320 (MSS x 46)

bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 10454.4 kbps (1306.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4181.76 kbps (522.72 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON
Time to live left = 57 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Non ci capisco una mazza
