[Gluster-users] glusterfs and glusterfsd process utilization

I haven't heard anything from anyone re this post yet so I have a bit more
info to add.  The last time I posted about extremely high process
utilization for glusterfs and glusterfsd, I was asked to see if I could
capture the output of a profile.  I did so and here is the output of 2
captures (they appear very similar).  Perhaps this will assist.  Note that
previously I was mounting with the fuse client.  This time I tried NFS.

Profile Output 1:
Brick: 192.168.10.92:/export/brick1
