Non l'ho mai chiesto ma come sono questi valori della mia linea alice 640/256?

TCP options string = 020405b40402080a0039a12a0000000001030302
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.
Default Receive Window (RWIN) = 5840
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 1460
RWIN is 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: 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 = 54 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 (0)
I valori di rwin li ho settati ma con linux mi rileva sempre 5840...
