Forgot to mention: on a client system (not a brick) the
glusterfs process is consuming ~ 68% CPU continuously. This is a much less
powerful desktop system so the CPU load can't be compared 1:1 with the
systems comprising the bricks but still very high. So the issue seems to
exist with both glusterfsd and glusterfs processes.

Subject: high CPU load on all bricks
Gluster gurus ~
I've deployed and 8-brick (2x replicate) Gluster 3.3.1 volume on
CentOS 6.3 with tcp transport. I was able to build, start, mount, and use
the volume. On each system contributing a brick, however, my CPU usage
(glusterfsd) is hovering around 20% (virtually zero memory usage
thankfully). These are brand new, fairly beefy servers so 20% CPU load is
quite a bit. The deployment is pretty plain with each brick mounting the
volume to itself via a glusterfs mount. I assume this type of CPU usage is
atypically high; is there anything I can do to investigate what's soaking up
CPU and minimize it? Total usable volume size is only about 22 TB (about 45
TB total with 2x replicate).
Thanks,
~Mike C.
