Tuning Enterprise JavaBeans applications

Tuning EJB cache with trace service
The size of your Enterprise JavaBeans (EJB) cache can affect the performance of the application server. One of the steps in tuning your EJB container to optimum performance levels is to fine-tune the EJB cache.
Tuning the deployment of EJB applications
When the product deploys an enterprise bean (EJB) application, it searches for remote EJB beans. You can reduce the deployment time of applications that contain many EJB JAR files by setting the IBM-Enable-Remote-EJB-List attribute to true, even if your application does not contain any remote EJB beans.
EJB method Invocation Queuing
Method invocations to enterprise beans are only queued for remote clients making the method call. An example of a remote client is an Enterprise JavaBeans (EJB) client running in a separate Java virtual machine (JVM) (another address space) from the enterprise bean. In contrast, no queuing occurs if the EJB client, either a servlet or another enterprise bean, is installed in the same JVM on which the EJB method runs, and on the same thread of execution as the EJB client.
