I have seen Ceph clusters spike to several seconds per IO
operation as they were designed for the same goals.

Most likely they time
I'm going to assume that ALL of your pools are replicated with size 3, since
you didn't provide that info, and that all but the *hdd pools are on SSDs.
`ceph osd dump | grep pool`
Let me know if that isn't the case.
With that assumption, I make your pg ratio to be ~ 57, which is way too low.
