OK I remove it, and force nfs v3
$mount cobra3:/p2v5f1 -o async,wsize=32768,rsize=32768,nfsvers=3 /mnt/cobra3

It is about to take the same very long time :-(

However what stricks me is that although I asked for r&wsize of 32 K , 
looking at /proc/mounts show :
$cat /proc/mounts
cobra3:/p2v5f1 /mnt/cobra3 nfs 
rw,v3,rsize=8192,wsize=8192,hard,tcp,lock,addr=cobra3 0 0

8 K r&wsize ??? I also tried with 16K it's still shows 8K ?, howerver 
moving from soft to hard did shows up in /proc/mounts .
Again, How can we check every options of an NFS mounted filesystem on 
the client side ? (other than /proc/mountd) .

thanks .
