I talked to someone on #fedora-admin about this and it is caused by
Koji having to load the metadata (files, dependencies etc) of every
RPM into its database. Combined with the fact this happens to be
running on s390x and it's texlive, makes it slow.
Can you be more specific? Is it slow because:
1. the s390x has a slow or inappropriate CPU for the task?
2. the VM on the s390x has not enough real RAM, and is page thrashing on a spinning harddrive?
3. the database uses a quadratic algorithm that hurts in this case?
4. the database has very high CPU overhead in general?
5. "every RPM" means all 30,000 .rpm in Fedora, not just the 300 for texlive?
(And if so, then why isn't tagging slow for _every_ package?)
6. some other specific reason(s)?
Indexing 1GB of data should take no more than a few minutes.
