I would look at what you are trying to do first. 1000 queries in 3 mins is about 5.5 per second. Do you have to run them individually? Can you send a single DB request to fulfil many - say 100, then parse the result? Have you found out where the issue lies? Is it the database, the transport, the client processing? Is something else interfering? Is it table scanning anywhere? Is the database designed for this query or does it need restructuring? Is it suffering from fragmentation and needs some maintenance? If you haven't done it already I would start by taking all the queries that you are running and just run them on the database and output the results to a table to see how long that takes to see whether the problem is the database or elsewhere.
