Sorry, should have provided more details. Version was glusterFS 3.0.3 
from git checkout. We tried 4 node (2servers/2clients) with 
favorite-child and 2 node (client/server same node) with read-subvolume 
pointing to the local node. (plus a boatload of variations with 
translators).

But as I said, and what you can gather from the list-archives, reported 
performance differs wildly so there is no way around testing your own 
platform.
