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. http://oprofile.sourceforge.net/ Feel free to contact us for any further help. You can also reach us on IRC (#gluster on irc.freenode.net). Vikas -- http://vikas.80x25.org/
