Session Bean Performance

To improve session bean performance, consider the following:

Bean Instance Pooling

For session beans, using bean instance pooling can increase performance by reducing bean creation overhead. For more information, see "Managing the Bean Instance Pool".

Singleton Interceptors

For EJB 3.0 session beans, if you are using interceptors and your interceptors are stateless, you can specify singleton interceptors. This OC4J EJB 3.0 extension creates a singleton for each interceptor class. This singleton is shared by all session bean instances that use that interceptor class. This reduces memory requirements and life cycle management. For more information, see "Singleton Interceptors".
