Hi Prashant, 8 seconds as the minimum time is a little too much, though considering you're using just 4G of RAM its still ok. I would advice you to break your index into smaller indexes, perhaps selectively query the indexes (if that's possible for your application) and use a parallelmultisearcher. Its just something that you might try and like. All said and done, parallelizing would only get you a bell-curve like performance graph, so you'd have to figure out the sweet spot there.
