Remote vs Local Interfaces in JBoss 3.0 Alpha

[thorntond]

I performed some timing tests on remote interfaces within the same JVM in JBoss 3.0 Alpha. From my timing tests it appears that the remote interfaces are optimized not to make RMI calls when the EJBs are in the same JVM. Can someone verify if this is the case? If this is the case, would there be any performance gains by implementing Local Interfaces on EJBs?

Whooops! I performed the timing tests on JBoss 3.0 beta, not JBoss 3.0 alpha. The question about Local vs Remote interfaces is in regards to JBoss 3.0 beta.

By default JBoss uses local inside the same VM, even
when you don't code local.
This was also true in JBoss 2.4

There is a further optimization on the way with the
next release because of the unified classloading.
Look at this modification.

This is great. So no need to bother with implementing local interfaces in JBoss.
