This isn't surprising at all. The Mac Mini's are well known to have very

Hmm. Bummer. Is there anything I can do to improve the situation? Can
htdig be told to keep it's data in RAM or something?
Supposedly you can upgrade the Mac Mini hard drives and see noticeable
improvements in performance. You should be able to find quite a few
articles on this issue if you search around the web. However depending
on your needs the money might be better spent scraping together the
pieces for a generic PC or picking up a used G4 if you need to go with a
Mac. ht://Dig ran fairly well on one of my old G4's both under OS X and
Yellow Dog.
I am not sure that there is much you can do at the ht://Dig level that
will significantly improve performance. You might try playing with the
database compression level and the size of the stored excerpts.
