velox adsl speed test

[thekloo]

ciao volevo sapere quale velocita' media puo' essere considerata "buona" con una adsl 640 alice?

[seclimar]

70 / 80 kbytes al secondo in download!

(ma non testata con i p2p .. mi raccomando)

[thekloo]

il fatto è che con lo speed test di tin.it mi da una media di circa 300 kbit/sec(ovviamente senza fare altro)non dovrebbe essere piu' vicina ai 600?

ecco qui:
TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 32120
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 32120

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)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 1284.8 kbps (160.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 513.92 kbps (64.24 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

I settaggi sono a posto.

Prova un trace su www.ngi.it

[thekloo]

prima di tutto grazie per l'aiuto...scusa la mia ignoranza ma trace su www.ngi.it?devo fare il ping? :tongue:

Vai in dos e scrivi

a me da questo... devo modificare rwin secondo voi?
