Think you have an unusual setup there. Generally Gluster would be used to
_either_ provide Gluster _or_ NFS shares from 10.1.4.181 and 10.1.40.2. So
you'd have (1) and (3) in a normal setup, no (2).
Also, I don't believe you can get aggregate speeds out of it, since each
replica needs to receive everything, and it's synchronous. So if your write
goes to .181, then .181 has to write to .2 before the operation is done, and
it just has a single connection to .2, not an aggregate one.
