ADSL MEGA 1280/256 attiva da oggi... up from 640/128
Finalmente….! Pero” sono stati veloci… solo 8 giorni lavorativi per avere la mega!
E quindi:

Your download speed: 1065391 bps, or 1065 kbps.
A 130 KB/sec transfer rate.
Your upload speed: 280112 bps, or 280 kbps.
Seems like broadband .. above the 1mbit barrier!
Mi chiedo pero” se devo apportare qualche tweak? Questo era settato per la ADSL 640/128?
TCP options string = 020405ac0103030001010402
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 MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 31944
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 31944
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 1277.76 kbps (159.72 KBytes/s) @ 200ms
Your RcvWindow limits you to: 511.104 kbps (63.888 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) = 01011100
Precedence (priority) = 100 (flash override)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 0 (normal reliability)
Cost = 1 (low cost)
Aiuto e...
Grazie
