It's a little four host, 4 OSD/host HDD cluster with a 5th doing the
non-osd work. Nearly entirely cephfs load.

Is this on SSD or HDD? RGW index, RBD, or ...? Those all change the
math on single-object recovery time.
Having said that...if the object is not huge and is not RGW index
omap, that slow of a single-object recovery would have me checking
whether I have a bad disk that's presenting itself as significantly
underperforming.

Might someone explain why the count of degraded items can drop
thousands, sometimes tens of thousands in the same number of hours it
takes to go from 10 to 0? For example, when an OSD or a host with a few
OSD's goes offline for a while, reboots.
Sitting at one complete and entire degraded object out of millions for
longer than it took to write this post.
Seems the fewer the number of degraded objects, the less interested the
cluster is in fixing it!
