"EJB3 is slow sometimes" To view the discussion, visit: https://community.jboss.org/message/799317#799317 -------------------------------------------------------------- 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.
