[pbs-devel] Authentication performance

Yes, we will keep that in mind.

They are all ZFS based, so not sure if that helps.

This might help, at least. Thanks!

So looking further into this, I noticed an average of ~ 70 calls per 
second on:
/api2/json/admin/datastore/.+/status

I think that is `pub async fn status()` in that same file, right? 
Nothing much to tune there.

Thanks again, I will keep you posted on the progress after our 
maintenance window.
