Hi there

I have EJB Bean on JBoss 5 and remote client (webapp on tomcat 7).

When I have 10-20 requests per second from Tomcat to JBoss EJB, the EJB request invocation time on tomcat takes about 100-150ms, on JBoss it takes about 100-140ms (same time).
But when I have 200 requests per second from Tomcat to JBoss EJB, the request invocation time on tomcat takes abount 5000-6000ms, but on JBoss it takes only 1000-1200ms.

Why so different results? Where is the limitation can be?

As far as I see there are only 50 WorkerThreads. Where can I increase the limitation?

I suppose "on Tomcat" you mean Tomcat server doing a remote EJB invocation that is running on the JBoss and you are comparing this to local calls?

You should take a look at remoting-jboss-beans.xml and look at pool sizes and try to tune them to get better numbers.
