Something like smallfile perhaps? https://github.com/bengland2/smallfile
Or you just time creating/reading lots of files
With read benching you would want to ensure you've cleared your mds cache or use a dataset larger than the cache.
I'd be interested in seeing your results, I this on the to do list myself.

ceph osd pool get fs_meta crush_rule
ceph osd pool set fs_meta crush_rule replicated_ruleset_ssd
I guess this can be done on a live system?
What would be a good test to show the performance difference between the
old hdd and the new ssd?
