Bonjour,
Mon problème est que le transfert de fichiers samba est très long (environ 800 ko/s) et je ne comprend pas pourquoi.
Il s’agit de transfert depuis un disque dur externe usb vers un poste windows7 en utilisant samba.
Tests réalisés :
samba linux (disque dur externe) -> win7 : 700 ko/s
ftp linux (disque dur externe) -> win7 : 8 mo/s
afp/netatalk : 8 Mo/s
rsync linux (disque dur externe) -> /dev/null : 30 mo/s
rsync linux (disque dur externe) -> ~ (carte micro sd interne, où est installé linux) : 4.4 mo/s
Voici ma config :
