Performance testing NESE storage #411

Closed larsks closed 3 years ago

larsks commented 3 years ago

Either run our own performance tests or find someone with existing experience evaluating openshift storage to perform the testing for us.

larsks commented 3 years ago

I put together a small project that runs fio against our two storage backends.

The tests run for 60 seconds, and produce the following metrics:

My reading of the results is that the Ceph storage is comparable to the NFS storage.

I've included visualizations of these metrics below; these were produced using the analyze.py script from the project repository.

@larsks do we have a link to the project you created for this that would allow others to run the same test?

larsks commented 1 year ago

@joachimweyl yes, it's linked from an earlier comment: https://github.com/larsks/k8s-storage-profiler

@joachimweyl we should probably be having this discussion here, since that issue is still open and is targeted at the NERC environment.
