The results above show that in general EclipseLink with HSQLDB server is much more efficient than DataNucleus with DB4O embedded in performing JPA database operations. Comparing the normalized speed of DataNucleus with DB4O embedded database (1.4) to the normalized speed of EclipseLink with HSQLDB database server (8.6) reveals that in these tests, EclipseLink with HSQLDB server is 6.1 times faster than DataNucleus with DB4O embedded.

A huge performance gap has been detected when using simple basic entities with small transaction/retrieval size. Comparing the normalized speed of DataNucleus with DB4O embedded database (0.24) to the normalized speed of EclipseLink with HSQLDB database server (5.4) reveals that in that case, EclipseLink with HSQLDB server is 22.5 times faster than DataNucleus with DB4O embedded.
