Java/CORBA and EJB components benefit from most of the settings described in “Common component performance issues”.
You can improve the performance of Java/CORBA and EJB components by configuring common class loaders for the application’s components (including Web components). EAServer uses custom class loaders to allow you to refresh implementation classes without restarting the server. Loading multiple copies of the same class uses memory unnecessarily. You can eliminate redundant class loading by configuring an application-level or server-level class list, as described in Chapter 10, “Configuring Java Class Loaders,” in the System Administration Guide.
