Con diversi tentativi non sono ancora riuscito a settare la mia 7 mega Alice con
il semplice programmino che si trova su www.dslreports.com e che
si chiama DRTCP021 Guida: http://www.anarchia.com/link_in_frame.php?link=903&c=
Questo e il test di speedguide:
IP Address: 95.235.204.11 (95.235.204.11)
Client OS: Windows XP
Browser: Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6 ( .NET CLR 3.5.30729)
Please Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405ac0103030201010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.
Default TCP Receive Window (RWIN) = 261360
RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)
Unscaled TCP Receive Window = 65340
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
63888 (up to 2 Mbit lines, depending on latency. MSS * 44)
127776 (1-5 Mbit lines, depending on latency. MSS * 44 * 2)
255552 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2)
511104 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3)
1022208 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 10454 kbps (1307 KBytes/s) @ 200ms
Your TCP Window limits you to: 4182 kbps (523 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)
