Hi,
We have EJB(EJB3.0) application which is deployed on JBoss 5.0, we feel sometimes EJB takes long time to return the data(data volume is always same) to invoker.
@Stateless(name = "RequiresNewSessionBean")
@RemoteBinding (jndiBinding = "N_All/RequiresNewSessionBean/remote")
@LocalBinding (jndiBinding = "N_All/RequiresNewSessionBean/local")
@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
com.test.ejb.RequiresNewSessionBean
com.test.ejb.LocalSessionBeanInvoker (this class has only invoking parts) will invoke "com.test.ejb.RequiresNewSessionBean"
As you see the below 3 scenarios, execution of "com.test.ejb.RequiresNewSessionBean" has been finished but it takes time to return to invoker.
The time taken is changing from "8 ms" to maximum "150 ms" in my local system.
But in our production server this time taken is went up to "3000 ms" (only sometimes not all the times, by default it will be within 1 ~ 2 ms in Production server)
Please share your suggestions to overcome this issue.
