As far as I know, they are. But I mainly use quotas for reporting purposes. I have not had much experience with enforcing quota limits in Lustre.

The last time we did performance testing, I think we only saw a performance hit of around 10%. But this was several years ago (i.e. - Lustre 1.8 days), so I don’t know how much things have changed since then.
