The performance of some inter-component calls in EAServer can be improved by enabling the lightweight container (LWC). The LWC co-exists with the standard container. The LWC provides optimized performance for EJB-to-EJB calls, while ensuring all expected EJB semantics are preserved such as pass by value when using remote interfaces. For more information, see “Optimizing in-server EJB calls” in in Chapter 3, “Component Tuning,” in the EAServer Performance and Tuning Guide.
