Dopo aver letto l'utilissimo post per la configurazione ed aver provato a smanettare un po sui vari parametri ho ottenuto questi risultati:

Io ho libero adsl affari a 1,2 MB (2.5 Mbps)

Sono ottimali tali valori ho devo configurarli meglio ?

TCP options string = 020405b40103030001010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 31944
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 31944

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 1277.76 kbps (159.72 KBytes/s) @ 200ms
Your RcvWindow limits you to: 511.104 kbps (63.888 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON

Time to live left = 119 hops

TTL value is ok.
Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000
