If you don't mind dirty reads you can try putting (NOLOCK) after your table names in your SELECT queries. The trade off here is that you are not guaranteed the most up to date data as UPDATE and INSERT statements currently executing are ignored.
Usually this is not to much of a train-smash as most systems read far more than they update/insert, but obviously it depends on the nature of your application.
