I'm following up on this as we upgraded to Pacific 16.2.9 and deletes
are still incredibly slow. The pool rgw is using is a fairly small
erasure coding pool set at 8 + 3. Is there anyone who's having the same
issue?

Hi,
First of all, a quick google search shows me that questions about the
s3 API slow object deletion speed have been asked before and are well
documented. My issue is slightly different, because I am getting
abysmal speeds of 11 objects/second on a full SSD ceph running Octopus
with about a hundred OSDs. This is much lower than the Redhat reported
limit of 1000 objects/second.
I've seen elsewhere that it was a Rocksdb limitation and that it would
be fixed in Pacific, but the Pacific release logs do not show me
anything that suggest that. Furthermore, I have limited control over
the s3client deleting the files as it's a 3rd-party open source
automatic backup program.
Could updating to Pacific fix this issue? Is there any configuration
change I could do to speed up object deletion?
