The results above show that in general EclipseLink with HSQLDB server is more efficient than Hibernate with Derby embedded in performing JPA database operations.

A large performance gap has been detected when using simple basic entities with large transaction/retrieval size. Comparing the normalized speed of Hibernate with Derby embedded database (6.7) to the normalized speed of EclipseLink with HSQLDB database server (15.8) reveals that in that case, EclipseLink with HSQLDB server is 2.4 times faster than Hibernate with Derby embedded.
