Really this depends on how you do the search, what your database is and how
it is indexed.
We have a site doing 12,000 page impressions a day from around 18,000 items
on a PIII 700MHz with 512MB RAM. Load average is around 0.2 at peak times.
Site is IC5.0 / MySQL.
In your case you may find the amount of swapping unacceptable and this will
cause increased latency and higher CPU load. Memory is cheap - put some more
in and try it. Also, sensible database indexing and [timed-build] are your
