index files into a number of data files, etc.

ally CPU-intensive, while
pulling Documents is I/O-bound. And RAM is about 5 or 6 orders of
magnitude faster than disk I/O.

I am going over ways to increase overall search performance.
Currently, I have a dual zeon with 2G of ram dedicated to java searching an
8G index on one 7200 rpm drive.
Which will give the greatest payoff?
1) Going to 64bit server and giving more memory to java with faster
drive
Curious... what kind of search performance are you getting for an index this
size...

sure to specify the sort type as an int and
see if that improves performance. I'm pretty certain you'd still get
better performance by using a boost than a sort though.

Using boosts will definitely use less resources than sorting. If you
do use sorting for dates, be sure you're doing it numerically rather
than lexicographically.

I have a large index that needs to yield very fast query times. I am
sorting by date as default since I am interested in the most recent
documents. I was wondering if I boosted the score of my documents in
proportion to the date and not sorting would this increase search
performance. Thoughts?
