Hi Folks,
I thought I would mention that I've released a couple of performance
articles on the Ceph blog recently that might be of interest to people:
For sure, thanks a lot, it's really informative!
Can we also ask for special requests? One of the things that would
help us (and CephFS users in general) is how performance of CephFS for
small files (~512 bytes, 2k up to say 64K) is impacted by the amount
of PGs a CephFS metadata pool has.
That's an interesting question. I wouldn't really expect the metadata
pool PG count to have a dramatic effect here at counts that result in
reasonable pseudo-random distribution. Have you seen otherwise?
I can't tell for sure yet. I'm going to perform some tests myself to try
to figure it out.
Gr. Stefan
