I should add that while what you are trying to do IS supported by Ganesha, assuming all the required directories exist, it is best when using FSAL_VFS or FSAL_GPFS exports...

You're welcome and sorry that this was confusing what was necessary. Can we close this now?

There's also an older ganesha/cephfs performance issue: #499. I'm going to keep this newer one since it has recent activity and close the older one as a duplicate.

We are working on some issues here. We have done some work to address ceph memory use which might have an impact.

Yes, that's another thing we need to work on. Ideally we would just point the write data at the original buffer. And at some point, we need to support a...

What would you be looking for in such a client? What is the use case?

> My interest is in fine-grained performance testing, feature prototyping, and related activities. That definitely sounds interesting. Would you want to simulate multiple clients, probably with some sort of synchronization?...
