A thread in the Remoting user forum ("JBREM-877: New Socket Connection is being Created for Every" - http://www.jboss.com/index.html?module=bb&op=viewtopic&t=126382) has brought up an interesting issue concerning the use of Remoting in EJB3. In AS 4.0.4/4.0.5, when EJB3 was using Remoting 1.4.x, each call to org.jboss.aspects.remoting.InvokeRemoteInterceptor.invoke() created a new org.jboss.remoting.Client, and when it returned, it left the underlying client invoker intact in the org.jboss.remoting.InvokerRegistry. The next call found the existing client invoker and reused its socket pool. (Simplifying somewhat, but basically true.) Now, in AS 4.2.x/5.0.0, each call to InvokeRemoteInterceptor.invoke() calls Client.disconnect() before returning, which, if the reference count of the underlying client invoker goes to zero, leads to the destruction of the client invoker, along with its socket pool. So, unless there are multiple proxies in the same JVM running simultaneously and keeping the client invoker's reference count above zero, each invocation will lead to the creation of a new socket. The guy that posted JBREM-877 says that performance is 25% of what it was in AS 4.0.4. One solution would be to add a feature which allows a delay in the destruction of the client invoker. E.g., the invoker locator | socket://${jboss.bind.address}:3873/?invokerdestructiondelay=5000 | would introduce a 5 second delay before the client invoker gets destroyed, increasing the probability that it would be reused. The default behavior would be to destroy the client invoker immediately. Any thoughts from the EJB3 team? -Ron View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130313#...
