ARTICOLO: come settare l'adsl al meglio

[fivendra]

quei valori che ti ho detto in tcp receive window
salvi e riavvi e testi

[fabiuccio]

mamma quanto sono ignorante...

cioè,al posto di 372300 devo scrivere 44?

[fivendra]

no, prendi il tuo valore di mss e lo moltiplichi per 44 o per 88 e così via..
il risultato lo metti su tcp receive window
salvi e riavvii e testi

che rwin è troppo basso...
prova questi valori

128480
e
64240

ciao
ho inserito rwin a 128480....per testare come faccio?
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 128480
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled Receive Window = 64240

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)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 58 hops

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



Grazie

Ciao a tutti.Ho l' adsl di libero in unbudling a 4mbit con modem fastrate 100 usb.
Ho fatto il test con speedguide ed ho ottenuto i seguenti valori:

MTU = 1500

Devo utilizzare doctor TCP per modificare qualche valore?? se si quali e come??
Aiutatemi a migliorare la mia connessione .
Grazie a tutti anticipatamente :

come ti sembra adesso?

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.

Timestamps (RFC1323) =

Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

[fivendra]

in teoria è ok, ma bisogna vedere se con questi valori riesci a spremere tutta la banda...
fai un pò di test

La mia navigazione è di una lentezza estenuante, ho provato le varie combinazioni, ma risulta sempre lenta.
Come posso intervenire?

gentile Fivendra , ho postato i miei risultati sopra.Volevo solo chiederti avendo una 4mega come Fabiuccio ma di Libero posso settare doctor tcp solo considerando il mio Mss(1460) moltiplicandolo per 88 o devo modificare qualche altra opzione?. Grazie e scusa il disturbo

[Robiccio]

ci capisco ben poco...AIUTOOO
uso un router wireless alice 1.2..
cosa metto in DRTCP021 ??


MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1360
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
