title: Speed up Hibernate EntityManager initialization
body: <p>I'm using the Hibernate JPA provider. It seems like it takes a tremendous amount of time (over 3 seconds) just loading the @Entity annotated classes and building various type trees and query trees. Is there any way to speed this up? It really makes unit tests a downer, even though it just happens once.</p>
  
  <p>I already turned off schema validation and update. Thanks.</p>
