JPA Performance Benchmark (JPAB)

Comparison of EclipseLink with PostgreSQL server vs EclipseLink with HSQLDB server

Each of the following tables focuses on a specific database operation, where the last table presents average results comparison.

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