Hi Drew,

During my tests on gluster v3, using 'disable.nfs: false' and using that as ovirt storage brought maximum performance for my 1 Gbit/s network.
Can you try using NFS and if it works well, you can disable nfs and get NFS Ganesha up and running.

It seems that FUSE in gluster v5 is performing way better, but still it is not the optimal solution.
