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

Transaction/Retrieval Size	Few Entities		Many Entities		Average Score
	OpenJPA MySQL server	EclipseLink HSQLDB server	OpenJPA MySQL server	EclipseLink HSQLDB server	OpenJPA MySQL server	EclipseLink HSQLDB server
Basic Person Test	1.0	5.4	5.3	15.8	3.2	10.6
Element Collection Test	0.79	4.8	2.9	failed	1.8	4.8
Inheritance Test	0.82	failed	4.2	failed	2.5	failed

The results above show that in general EclipseLink with HSQLDB server is much more efficient than OpenJPA with MySQL server in performing JPA database operations. Comparing the normalized speed of OpenJPA with MySQL database server (2.5) to the normalized speed of EclipseLink with HSQLDB database server (8.6) reveals that in these tests, EclipseLink with HSQLDB server is 3.4 times faster than OpenJPA with MySQL server.

A large performance gap has been detected when using JPA element collections with small transaction/retrieval size. Comparing the normalized speed of OpenJPA with MySQL database server (0.79) to the normalized speed of EclipseLink with HSQLDB database server (4.8) reveals that in that case, EclipseLink with HSQLDB server is 6.1 times faster than OpenJPA with MySQL server.
