That's a tiny number of files. Ought to be essentially instant.
I routinely have up to a million files in a directory. That can take
a few minutes to delete, but I don't have any SSDs at all on
those systems.

This isn't being done over NFS, is it? That can dramatically slow
operations like this, even with a log.
