Also, keep in mind that optimization is a very disk intense process (and therefore slow). It completely rewrites the index, and should only be done when you are not expecting the index to change for a while.

Have you checked out these pages? http://wiki.apache.org/lucene-java/ImproveIndexingSpeed http://wiki.apache.org/lucene-java/ImproveSearchingSpeed Even a large index should be fast, assuming the queries are not complicated. Also, with a large index the performance depends on the number of matches, i.e. searching for very common terms might be slow. Maybe you could post more information about your queries.
