ARTICOLO: come settare l'adsl al meglio

[fivendra]

hai solo il valore di rwin da modificare...
rwin dovrà essere pari a mss moltiplicato per 22
usa drtcp 021 come da guida, riavvia e sei ok
se proprio vuoi cala ttl a 64

[conca]

Dopo aver letto l'utilissimo post per la configurazione ed aver provato a smanettare un po sui vari parametri ho ottenuto questi risultati:

Io ho libero adsl affari a 1,2 MB (2.5 Mbps)

Sono ottimali tali valori ho devo configurarli meglio ?

occhio a non mettere più il tuo ip, non si sa mai
rwin va alzato, metti una valore pari a mss per 44

Adesso va meglio ?

per una 1,2mbit in su, si è ok!

Grazie per la dritta !!

mi sembra di capire che ci sono margini di miglioramento


TCP options string = 0204059801010402
MTU = 1472
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1432
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535

Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:

ho una 640
quale impostazione è migliore?
grazie

[fivendra]

che adsl hai?
modem usb, ethernet, router?
