Thank you Milosz. Since InnoDB is transaction-safe and it becomes the new default storage engine of MySQL I switched to the last MySQL version and now all the JPA implementations use MySQL with InnoDB.
I published the new results at: http://temp.jpab.org/All/All/All.html temp.jpab.org . The new results are based on using OpenJPA and DataNucleus after tuning, but still default configuration for Hibernate and EclipseLink. At the moment, OpenJPA is slightly faster than other JPA implementations with MySQL and PostgreSQL but slightly slower than Hibernate with HSQLDB & H2 and EclipseLink with Derby in embedded mode. -- View this message in context: http://openjpa.208410.n2.nabble.com/JPAB-results-tp5693298p5766716.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
