Perhaps one thing to try is a partial optimize
(IndexWriter.optimize(int maxNumSegments)). It makes optimize faster,
but searches may run slower than a full optimize.
EG, optimize(5) will reduce index to <= 5 segments.

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.

from my
research on the internet the Lucene version 2.3 is much faster and
better so why are we seeing such inconsistency.
Have you checked out these pages?

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.
