Inheritance Test		stopped		stopped		stopped
Indexing Test		stopped		stopped		stopped
Graph (Binary Tree) Test		stopped		stopped		stopped
Multithreading Test		stopped		stopped		stopped
All Tests		stopped		stopped		stopped

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

Retrieval Size =>	Few Entities		Many Entities		Average Score
	DataNucleus SQLite embedded	Hibernate HSQLDB server	DataNucleus SQLite embedded	Hibernate HSQLDB server	DataNucleus SQLite embedded	Hibernate HSQLDB server
Basic Person Test	0.43	stopped		stopped	0.43	stopped
Element Collection Test		stopped		stopped		stopped
Inheritance Test		stopped		stopped		stopped
Indexing Test		stopped		stopped		stopped
Graph (Binary Tree) Test		stopped		stopped		stopped
Multithreading Test		stopped		stopped		stopped
All Tests	0.43	stopped		stopped	0.43	stopped

The results above show that in general DataNucleus with SQLite embedded is much more efficient than Hibernate with HSQLDB server in retrieving JPA entity objects from the database. Comparing the normalized speed of Hibernate with HSQLDB database server (0.0000) to the normalized speed of DataNucleus with SQLite embedded database (0.43) reveals that in these tests, DataNucleus with SQLite embedded is ? times faster than Hibernate with HSQLDB server.

All Tests	0.025	stopped		stopped	0.025	stopped

The results above show that in general DataNucleus with SQLite embedded is much more efficient than Hibernate with HSQLDB server in updating JPA entity objects in the database. Comparing the normalized speed of Hibernate with HSQLDB database server (0.0000) to the normalized speed of DataNucleus with SQLite embedded database (0.025) reveals that in these tests, DataNucleus with SQLite embedded is ? times faster than Hibernate with HSQLDB server.

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

Transaction Size =>	Few Entities		Many Entities		Average Score
	DataNucleus SQLite embedded	Hibernate HSQLDB server	DataNucleus SQLite embedded	Hibernate HSQLDB server	DataNucleus SQLite embedded	Hibernate HSQLDB server
Basic Person Test	0.17	stopped		stopped	0.17	stopped
Element Collection Test		stopped		stopped		stopped
Inheritance Test		stopped		stopped		stopped
Indexing Test		stopped		stopped		stopped
Graph (Binary Tree) Test		stopped		stopped		stopped
Multithreading Test		stopped		stopped		stopped
All Tests	0.17	stopped		stopped	0.17	stopped

The results above show that in general DataNucleus with SQLite embedded is much more efficient than Hibernate with HSQLDB server in deleting JPA entity objects from the database. Comparing the normalized speed of Hibernate with HSQLDB database server (0.0000) to the normalized speed of DataNucleus with SQLite embedded database (0.17) reveals that in these tests, DataNucleus with SQLite embedded is ? times faster than Hibernate with HSQLDB server.

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

Transaction/Retrieval Size	Few Entities		Many Entities		Average Score
	DataNucleus SQLite embedded	Hibernate HSQLDB server	DataNucleus SQLite embedded	Hibernate HSQLDB server	DataNucleus SQLite embedded	Hibernate HSQLDB server
Basic Person Test	0.21	stopped		stopped	0.21	stopped

Multithreading Test		stopped		stopped		stopped
All Tests	0.21	stopped		stopped	0.21	stopped

The results above show that in general DataNucleus with SQLite embedded is much more efficient than Hibernate with HSQLDB server in performing JPA database operations. Comparing the normalized speed of Hibernate with HSQLDB database server (0.0000) to the normalized speed of DataNucleus with SQLite embedded database (0.21) reveals that in these tests, DataNucleus with SQLite embedded is ? times faster than Hibernate with HSQLDB server.

A huge performance gap has been detected when using simple basic entities with small transaction/retrieval size. Comparing the normalized speed of Hibernate with HSQLDB database server (0.0000) to the normalized speed of DataNucleus with SQLite embedded database (0.21) reveals that in that case, DataNucleus with SQLite embedded is ? times faster than Hibernate with HSQLDB server.
