The results above show that in general Hibernate with H2 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 Hibernate with H2 database server (3.4) reveals that in these tests, Hibernate with H2 server is 6.5 times faster than EclipseLink with SQLite embedded.

A huge performance gap has been detected when using database indexes with small transaction/retrieval size. Comparing the normalized speed of EclipseLink with SQLite embedded database (0.058) to the normalized speed of Hibernate with H2 database server (4.6) reveals that in that case, Hibernate with H2 server is 79.3 times faster than EclipseLink with SQLite embedded.
