Comparison of JPA/Database speed - the averages (normalized score, higher is better)

Transaction/Retrieval Size	Few Entities		Many Entities		Average Score
	EclipseLink HSQLDB server	OpenJPA H2 server	EclipseLink HSQLDB server	OpenJPA H2 server	EclipseLink HSQLDB server	OpenJPA H2 server
Basic Person Test	5.4	3.7	15.8	5.7	10.6	4.7

The results above show that in general EclipseLink with HSQLDB server is more efficient than OpenJPA with H2 server in performing JPA database operations. Comparing the normalized speed of OpenJPA with H2 database server (4.0) to the normalized speed of EclipseLink with HSQLDB database server (8.6) reveals that in these tests, EclipseLink with HSQLDB server is 2.2 times faster than OpenJPA with H2 server.

A large performance gap has been detected when using simple basic entities with large transaction/retrieval size. Comparing the normalized speed of OpenJPA with H2 database server (5.7) to the normalized speed of EclipseLink with HSQLDB database server (15.8) reveals that in that case, EclipseLink with HSQLDB server is 2.8 times faster than OpenJPA with H2 server.
