Posto anche il mio di una ADSL tin.it 256 cosi' possiamo fare paragoni.
Onestamente non ci ho capito molto in questo test ( specialmente dopro Unscaled Receive Windows...qualcuno me lo spiega?
Fool, di ping non sei male.

MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 255552
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 63888

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:

Your RcvWindow limits you to: 10222.08 kbps (1277.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4088.832 kbps (511.104 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

Direi che per una 256 hai un valore di RWIN esagerato.

Ti consiglio RWIN=17520

Questi valori sono di una 320 Tiscali Light...come potete immaginare la mia banda è utilizzata a metà! 130kbit in download e 100 in upload..NON SI PUO' FAR NIENTE OLTRE A DEMOLIRE TISCALI???

Your RcvWindow limits you to: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 121 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON

lo so il ping è buono :sexpulp:

tu a quanto pinghi ?
