Hi Anton, For a strait gluster vs native; sysbench ( http://sysbench.sourceforge.net/docs/#fileio_mode also available from epel for el6 http://koji.fedoraproject.org/koji/buildinfo?buildID=262308) may be able to show some insight into guest I/O performance; over an extended period of time.
Potentially you could then look at concurrency by running sysbench on multiple guests to gauge degradation of performance due to concurrent I/O across nodes (if any exists), here I'd be particularly curious if high I/O on one compute node, due to replication caused a performance "hit" on another node.
