Why not close the connection as soon as you are done with the database operation. That way you don't need that many connections open all the time. Getting a new connections does not take much time if you are using some kind of connection pooling. I have one application which uses atmost 6 connections when there are 100 users working. I don't know your requirement. Just a suggestion.
