Two popular benchmarks in the HPC space for testing distributed file
systems are IOR and mdtest. Both use MPI to coordinate processes on
different clients. Another option may be to use fio or iozone. Netmist
may also be an option, but I haven't used it myself and I'm not sure
that it's fully open source.
If you are only interested in single-client tests vs a local disk, I'd
personally use fio.

I have set up a ceph storage cluster and I'd like to utilize the cephfs

without using the API).
To do so, I have mounted my cephfs on the client node.
I'd like to know what would be a good benchmark for measuring write and
read performance on the cephfs compared to the local filesystem?
Thanks,
Hadi
