Uh, as an update/follow-up on this:

I did not do a complete OS reinstall, but performed a fresh bootstrap installation of Fink as
described above, on an APFS volume here. I am still in the process of producing new builds
of all packages from my old installation (currently at ~50%), but while the scanning process
sped up reasonably right after setting up the new Fink, it started moving back to several minutes
after updating more packages. The Packages.gz file at least is rebuilt correctly, but the extreme
sluggishness appears in a different light after I found this in /sw/var/lib/fink:

-rw-r--r--   1 root  wheel  37425774592 Dec  2 00:08 scanpackages.db

- compared to a ~11 MB file in the old installation with about twice as many packages.
For perspective, this is over 12x the total size of all .debs or 4x the total installed size of the
Fink system. It’s just been completely rebuilt (taking O(40 min)) after deleting the previous instance
(and had almost blown up my Time Machine before I thought of excluding /sw/var from backups…).

I don’t know much about the Berkeley DB format or the internals of the Fink bookkeeping system,
has anyone got an idea what might be going on there, or could confirm if they are seeing similar
on APFS?

Cheers,
				Derek
