ceph_vms performance

[Thomas Bennett]

Hi,

I'm testing out ceph_vms vs a cephfs mount with a cifs export.

I currently have 3 active ceph mds servers to maximise throughput  and when
I have configured a cephfs mount with a cifs export,  I'm getting a
reasonable benchmark results.

However, when I tried some benchmarking with the ceph_vms module, I only
got a 3rd of the comparable write throughput.

I'm just wondering if this is expected, or if there is an obvious
configuration setup that I'm missing.

Kind regards,
Tom
