Speed comparison of JPA database update operations (normalized score, higher is better) Transaction Size => Comparing the normalized speed of Hibernate with PostgreSQL database server (0.016) to the normalized speed of Hibernate with MySQL database server (0.53) reveals that in that case, Hibernate with PostgreSQL server is 33.1 times slower than Hibernate with MySQL server.
On the other hand, Hibernate with PostgreSQL server is slower, for instance, when using JPA element collections with large retrieval size. Comparing the normalized speed of Hibernate with MySQL database server (2.1) to the normalized speed of Hibernate with PostgreSQL database server (55.2) reveals that in that case, Hibernate with PostgreSQL server is 26.3 times faster than Hibernate with MySQL server. Comparing the normalized speed of Hibernate with MySQL database server (2.9) to the normalized speed of Hibernate with PostgreSQL database server (20.7) reveals that in these tests, Hibernate with PostgreSQL server is 7.1 times faster than Hibernate with MySQL server.Ī huge performance gap has been detected when using multithreading with small retrieval size. The results above show that in general Hibernate with PostgreSQL server is much more efficient than Hibernate with MySQL server in executing the tested JPA queries. Speed comparison of JPA database query operations (normalized score, higher is better) Retrieval Size => Comparing the normalized speed of Hibernate with PostgreSQL database server (0.017) to the normalized speed of Hibernate with MySQL database server (1.2) reveals that in that case, Hibernate with PostgreSQL server is 70.6 times slower than Hibernate with MySQL server. Comparing the normalized speed of Hibernate with MySQL database server (0.23) to the normalized speed of Hibernate with PostgreSQL database server (11.3) reveals that in that case, Hibernate with PostgreSQL server is 49.1 times faster than Hibernate with MySQL server. The results above show that in general Hibernate with PostgreSQL server is more efficient than Hibernate with MySQL server in retrieving JPA entity objects from the database.Ī huge performance gap has been detected when using multithreading with small retrieval size. Speed comparison of JPA database retrieval operations (normalized score, higher is better) Retrieval Size =>
Comparing the normalized speed of Hibernate with MySQL database server (2.9) to the normalized speed of Hibernate with PostgreSQL database server (13.9) reveals that in that case, Hibernate with PostgreSQL server is 4.8 times faster than Hibernate with MySQL server. Comparing the normalized speed of Hibernate with MySQL database server (2.8) to the normalized speed of Hibernate with PostgreSQL database server (7.7) reveals that in these tests, Hibernate with PostgreSQL server is 2.8 times faster than Hibernate with MySQL server.Ī large performance gap has been detected when using multithreading with large transaction size. The results above show that in general Hibernate with PostgreSQL server is more efficient than Hibernate with MySQL server in persisting JPA entity objects to the database. Speed comparison of JPA database persistence operations (normalized score, higher is better) Transaction Size => Compare with Comparison of Hibernate with MySQL server vs Hibernate with PostgreSQL serverĮach of the following tables focuses on a specific database operation, where the last table presents average results comparison.
