I did play around with the searches, and your right. When I use criteria that causes fewer hits the search is much faster. So it looks like everything is normal. Would there be any advantage in using 3.2, since a lot of my searches may return many hits?

How does the server respond? Does it seem like it's starting to page?
Have you tried running htsearch from the command-line? If so, does it
seem like the slowdown is from htsearch itself or from some sort of

Remember that it's not going to scale linearly with the disk space of
the database. That's an important factor since many searches are
bounded by the number of disk accesses. But the searches are more
closely bound to the number of word matches. So if you're doing
searches for very common words, it's bound to take longer since more
matches must be scored.
You said you're running this on a Sun box, so I can't say you should
switch to a faster disk. :-) But how much RAM does it have?
