So just at a super quick glance - Before we start to anything else. You should modify the code to use the same (identical) random data for both tests. Add hibernate.jdbc.batch_size = 25 to your persistence.xml properties Never use @Stateful unless you really understand why you should, i.e. use @Stateless for your JpaMovies Use entityManager#find rather than a query
Hope this is a quick insight, but I'd also be interested to see the results on just these few changes. Andy.
