Most J2EE applications have EJB components that are called from other EJB components and the Web tier (servlets and JSPs). You can use the following techniques to optimize these calls:
Local interfaces, introduced in the EJB 2.0 specification, improve performance by eliminating the marshalling of parameter data; in other words, parameters in component calls are passed as local data references rather than copying the object.
You can also enable Pass-by-reference semantics in EAServer to achieve the same benefits as local interfaces when code invokes components through the remote interface.
