codice:
TCP options string = 020402000103030001010402
MTU = 552
MTU value is too small ! Consider increasing your MTU to 1500 for better throughput.
MSS = 512
MSS is not optimized for broadband. Consider increasing your MTU value.
Default Receive Window (RWIN) = 15972
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 15972
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
516096 (MSS x 126 * scale factor of 8)
258048 (MSS x 126 * scale factor of 4)
129024 (MSS x 126 * scale factor of 2)
64512 (MSS x 126)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 638.88 kbps (79.86 KBytes/s) @ 200ms
Your RcvWindow limits you to: 255.552 kbps (31.944 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
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
A me dice così, vedete? anmche se ho impostato l'mtu a 1492 e sia tcp optimizer sia dr.tcp sia dslreports mi riconoscono il valore di 1492 pero in speedguide continua a dirmi che sta a 552 perchè?
poi dice che rwin limita la banda a 79.86 vuol dire che mi conviene alzarlo leggermente?
