nfs performance

Grazie per la tua domanda, prova ad utilizzare:

$: sudo mount -t cifs 192.168.0.120://storage/cartella /mnt/storage

in modo da usare lo stesso protocollo di win. Grazie e ciao

Ho provato a montare il filesystem come cifs ma non cambia nulla.

grazie

Se dietro a un firewall in linux, mi puoi postare il risultato del ping al host 192.168.0.120 fatto sia da linux che da windows. Voglio capire se è un problema di scheda oppure di protocollo. Grazie

La risposta di 0.322 e buona. Prova a caricare il traffico con il seguente comando:

ping -l 512

così proviamo a testare la rete con pacchetti di 512 bytes. Vediamo la risposta. Fammi sapere.

ping -l 512 non funziona, ho lanciato ping -s 512 su rete WIRELESS

ciao

Scusa, hai ragione. L'opzione -l è sotto win. Ogni tanto confondo. la risposta non è belle. Provo io. Comunque dimmi se usi un firewall in linux, non vorrei che abbia impostato quelche politica particolare in uscita.

Ho installato firestarter

ciao

Su quale interfaccia hai configurato firestarter. Anch'io lo uso. Ho provato anch'io a fare il ping del mio disco di rete e ottengo gli stessi valori tuoi. Prova ad escluderlo per un attimo e rifare il test. Fammi sapere. (Sotto win usi qualche firewall). Ciao

l'interfaccia eth1(WIRELESS)
disabilitando il firewall i risultati sono circa gli stessi.
Credo che il problema non sussiste. Ho contattato DLINK e mi hanno fatto notare che la velocità che riportavo io era in byte e non in bit.
Quindi 3MB corrispondono a 24Mbit che è una velocità accettabile per un wireless 54Mbit(interferenze ecc.)

ciao
grazie

grazie ancora
