Regarding whether the filesystem cache helps, you could look at whether
there is some disk activity while your queries are running.
When everything is in the filesystem cache, the latency of search requests
for simple queries (term queries and combinations through boolean queries)
usually mostly depends on the total number of matches since Lucene needs to
call the collector on every match.
