OK, I've tried writing using pvfs2-cp, rsync and dd, and network
thruput reaches 120MB/s, so it's definetely more of a cp probem :) 

Another thing : I'm using bonding to aggregate bandwidth but pvfs2 uses
only one link, probably because pvfs2 uses only one socket; is it
possible to force it to use two or more connections when there are
several IOs going on?
