Grazie... ma non ci riesco! ho usato TCP optimizer sia versione V1. e V.2 MTU 1480 e MSS 1440 ? La Velocita' e tra 2.21/2.25 Mbps e 144/153 Kbps.
Non capisco perche' non lo setta?


MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1440
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 511200
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled Receive Window = 63900

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 20448 kbps (2556 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8179.2 kbps (1022.4 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON

Time to live left = 56 hops

TTL value is ok.
Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

o probabilmente la Telecom non ha ancora finito con il upgrade? e quindi devo aspettare?


Grazie
