non sono xniente un esperto pero' per quanto ho capito (se mi sbaglio qualcuno mi corregga) con ppoa devi settare mtu a 1500 e di conseguenza alzare il rwin

TCP options string = 020405a00103030201010402

MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 253464
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 63366
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:

ciao ragazzi, io ho Alice 4mb con i rubinetti aperti (PPoE)
ho modifica il rwin , ma ora ho picchi maggiori cosa che prima nn avevo!!!
tipo parte da 700kb/s e poi diventa costante (su debian)
prima invece no.
devo modificare pure Unscaled Receive Window??
grazie 1000
Cosa ne dite??? ho una adsl alice 4 mega! grazie a chiunque mi risponda in anticipo!!!!!

MTU = 1440
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1400
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.

ma come mai se imposto rwin usando drtcp a un valore poi mi ritrovo con quello di default dopo un po ? :\
secondo me è meglio se lo fai da router e poi salvi l'impostazione

Ho provato a cambiare le impostazioni con il programmino indicato in questa discussione ma come se non facessi nulla.
Mi collego con l'astronave nera della pirelli, via USB: devo cambiare qualche parametro nella configurazione del modem/router? Se sì come?
Prima avevo uno speedtouch e mi sembra che andava meglio!
Ciao.
salve a tutti
stasera proprio mi hanno aperto i rubinetti e scarico a 500kb...per ottimizzare il tutto che valori di rwin devo impostare??PS:ci sono altri parametri???fiveandra attendo lumi....grazie!!!
Cosa devo fare ?...ho pure seguito le iscruzioni...m non cambia molto.

io non ho capito una cosa.
Ma il rwin si calcola sempre mss x 22?
