I also did some test with balance-alb/balance-tld but i had some issues.
Please don't think about the bonding, i would like to get maximum
speed even with a single connection.

This is an iperf test made from the client to one of gluster server,
with bonding "balance-rr" and a single connection

$ iperf -c x
------------------------------------------------------------
Client connecting to x, TCP port 5001
TCP window size:  325 KByte (default)
------------------------------------------------------------
[  3] local 77.95.175.121 port 37324 connected with 1.2.3.4 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  2.31 GBytes  1.98 Gbits/sec

as you can see, with a single iper connection and balance-rr i'm able
to reach about 2gbit (i'm using 2 gigabit NIC bonded together)
