You said the host systems were also running the gluster client to have the
gluster mount locally available. Does the high load go away on them if you
unmount that? Some versions back (3.1.5), on some older systems (Ubuntu 8.04
with Gluster built from source), I had problems with the gluster client
running away on me. Those systems are happy using nfs mounts instead. And
the gluster servers, which aren't doing local mounting of gluster at all,
don't use much by way of CPU. Then again, they're not highly stressed by
use, so it's not much of a test.

That's a long winded way of asking, are you sure it's glusterfsd too, and
not just glusterfs sucking up the CPU cycles?
