Re: ceph osd perf on bluestore commit==apply

Yes, this is expected. Bluestore’s internal design differs a great deal from filestore, and it doesn’t have a distinction between the journaled and readable data the way filestore does with its separate journal and then normal xfs filesystem.

When I run 'ceph osd perf' on my cluster (12.2.2), for bluestore osd, the commit latency and apply latency are always equal.  This is not the case on filestore osd; the commit is lower or equal to apply.  Are the bluestore numbers expected behavior?
