Just to keep things simple, i've removed the bonding and I'm using a
single gigabit connection on each server.

These are some iperf results, made from the only client connecting to
this gluster cluster (via fuse/gluster):

Network seems to be fine but i'm still having low performances when
trying to extract the kernel sources or "dd" a huge file.
