ARTICOLO: come settare l'adsl al meglio

[PuNk3st4]

Salve ho Libero 4mb ed ho windows Xp...cosa ne pensate dei miei valori?se nn vanno bene in cosa devo cambiarli?:

TCP options string = 020405ac01010402
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) = 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:
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 (Note this is not a speed test):

Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 121 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

MTU = 1492

OK se sei in PPPoE.Se PPPoA meglio MTU=1500

Default Receive Window (RWIN) = 65535

Prova RWIN=255552 (256960 se metti MTU=1500)

[PuNk3st4]

sìsì sono in PPPoE..allora rimango tutto così com'è...grazie!..pero'noto che cmq ci sono parecchi sbalzi!

[PuNk3st4]

ops..intendevo dire ke andavo lento =P poi ho riletto meglio il msg..ora cambio rwin cavolo mi sn appena svegliato

sbalzi?anche io da quando ho cambiato rwin e l'ho messo a 130640 invece di 17.000 come era prima ho notato sbalzi ma ho notato anche che il test di mlink ora mi da pure 3.200kbps che prima non dava...boh

javipampa anche tu hai adsl libero 4mb?
cmq ecco ora speedguide mi da questo..va bene?(ricordo che ho l'adsl di libero a 4 mb)

Poi COn DRTCP ho settato questo...mi direste se vanno bene i parametri?

grazie

si anche io!ma l'mtu a me rimane ferma a 1460!

Si sono OK.

[javipampa2]

i miei?

attenuazione e rumore sono ok,vicinza dalla centrale è ok, ping ok

questo dlsrport e non c'è verso di alzare l'mtu

TCP options string = 0204058c0103030201010402
MTU = 1460
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

PuNk3st4 quanto fai col test mlink,libero,speedometro?
