Ideal value for single threadmodel pool size

[niraj l]

Hello ,     I have a servlet application with heavy database transaction. My classes implement SingleThread Model.     With 100 people accesssing the application simultaneously( we use a tool SQA Roboot to simulate it) what should be ideal value for "Single ThreadModel Pool Size"  in Jrun (jse settings).     Any quick help will really help me coz I am facing a production problem. Thanks, Niraj.
