OK, you also need to mention what version you are using, since this
makes a difference. :-) For example, the beta and developmental 3.2
code is slower at indexing right now, has smaller databases and
faster search.

Again, this depends on version. Also, you might want to turn on
excerpt compression with:
compression_level: 6
# or higher--this essentially turns on gzip compression

Also, these "indexes" include much more than the indexes themselves,
though you've certainly cut back on the stored excerpts drastically
with your max_head_length setting. Some search engines simply store a
word index, which you'll note is quite small.
