Each of the following tables focuses on a specific database operation, where the last table presents average results comparison.

Speed comparison of JPA database persistence operations (normalized score, higher is better)

All Tests	7.4	0.11	4.5	1.2	5.9	0.64

The results above show that in general OpenJPA with PostgreSQL server is much more efficient than EclipseLink with SQLite embedded in persisting JPA entity objects to the database. Comparing the normalized speed of EclipseLink with SQLite embedded database (0.64) to the normalized speed of OpenJPA with PostgreSQL database server (5.9) reveals that in these tests, OpenJPA with PostgreSQL server is 9.2 times faster than EclipseLink with SQLite embedded.

A huge performance gap has been detected when using multithreading with small transaction size. Comparing the normalized speed of EclipseLink with SQLite embedded database (0.10) to the normalized speed of OpenJPA with PostgreSQL database server (23.4) reveals that in that case, OpenJPA with PostgreSQL server is 234 times faster than EclipseLink with SQLite embedded.

The results above show that in general OpenJPA with PostgreSQL server is much more efficient than EclipseLink with SQLite embedded in performing JPA database operations. Comparing the normalized speed of EclipseLink with SQLite embedded database (0.52) to the normalized speed of OpenJPA with PostgreSQL database server (6.5) reveals that in these tests, OpenJPA with PostgreSQL server is 12.5 times faster than EclipseLink with SQLite embedded.

A huge performance gap has been detected when using multithreading with small transaction/retrieval size. Comparing the normalized speed of EclipseLink with SQLite embedded database (0.10) to the normalized speed of OpenJPA with PostgreSQL database server (18.7) reveals that in that case, OpenJPA with PostgreSQL server is 187 times faster than EclipseLink with SQLite embedded.
