There are a lot of variables there, including whether one uses KRBD or librbd for clients. I suspect that one can’t make a blanket statement either way.
Hi Anthony,
Your statement about MDS is interesting... So it's possible depending on the CPU-type that read/write operations on RBD will show a better performance than similar read/write operations on a CephFS?
MDS is single-threaded, so unlike most Ceph daemons it benefits more from a high-frequency CPU than core count.
