EJB 3.0 is supposed to drastically simplify EJB development, but at what cost? Peter Zadrozny and Raghu Kodali try to find that out by running and comparing the performance of an application over an EJB 2.1 and an EJB 3.0 setup.

The authors conclude that “We’re very attracted to the simplicity and power of EJB 3.0. The wonderful work done with annotations and the persistence, the ability to use POJOs, and the ability to test outside of the container are very attractive all by themselves. But now, with an implementation that equals or doubles the performance of EJB 2.1 (at least for our test cases), we can’t wait for the final specification and formal release of EJB 3.0. “

So it does look like EJB 3.0 has many things working for it and it might just replace a lot of cool tools like HibernateÂ
