nfsd on /proc/fs/nfsd type nfsd (rw)
/proc on /var/lib/dhcp/proc type none (ro,nosuid,nodev,bind)

It's all ext4, but as I've said same transfert by nfs is going to run at 
38-54MB compared to the 22-25MB seen by samba
(same file, same destination)

I don't understand the why or how ... I'm a bit lot, and the cold I have 
doesn't help to have clear ideas and efficient brain.
