Thanks for the response Hannes. The db will be read only.

Still looking for a response as to why cpu is so high when computations are
performed on the fs. Even when single node where traffic is sent back via
loopback. Can anyone answer this? Provide a solution to excessively high cpu
usage? Will have to try lustre next, but would prefer to stick with gluster
if this problem can be solved.
