I tried your setup (local client/server, 5 concurrent md5sum on a 300MB file)
but
unfortunately could not reproduce the issue. On my machine GlusterFS CPU usage
never goes above 10%.
I think the best way for you to diagnose this is to use the wonderful
system-wide profiling tool oprofile.

Feel free to contact us for any further help. You can also reach us on
IRC (#gluster on irc.freenode.net).
