EAServer provides a lightweight version of the standard EJB component container. The performance of some intercomponent calls in EAServer can be improved by enabling the lightweight container (LWC). The LWC coexists with the standard container. The LWC provides optimized performance for in-server EJB calls, while preserving all expected EJB semantics (such as pass by value when using remote interfaces). You can use the LWC for calls that use local or remote interfaces. The LWC can reduce CPU utilization for calls from session beans to entity beans, such that EJB-standard entity beans become as fast as lightweight persistence frameworks.
