Chiedo un consiglio a chi ne capisce di più ....
Sono un Utente fastweb con la 6 MB senza workstation , secopndo voi sono settati giusti i parametri??
Ecco i test :
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64240
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)
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: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 48 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
Dr.TCP settato cosi :
Tcp Receive Windows ........: 256960
Windows Scaling ............: Yes
Time Stamping ..............: No
Selective Acks .............: Yes
Dial Up (RAS) MTU ..........: Niente
Path MTU Discovery .........: Yes
Black Hole Detection .......: No
Max Duplicate ACKs .........: 2
TTL ........................: 64
Adapter Settings ...........: 3Com Gigabit LOM (3C940)
MTU ........................: 1500
