Bonjour à tous,

Je viens d'installer un DomU avec Samba (pour jouer le rôlr de NAS)
Je constate que les performances reseau sont mauvaises: (download de 30mins pour 200Mo)
Et l'upload est bien plus rapide.

Je ne sais pas trop ou regarder, je joins donc les ifconfig de dom0 et domU
- Je remarque au niveau du dom0 pour eth0, les valeur RX et TX semblent confirmer ma difference de debit entre le download et l'upload.
Mais rien sur domU...

Quelqu'un a t-il une idée où je pourrais chercher.

Merci d'avance
