JPA Performance Benchmark (JPAB)

Comparison of DataNucleus with DB4O embedded vs OpenJPA 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)

Transaction Size =>	Few Entities		Many Entities		Average Score
	DataNucleus DB4O embedded	OpenJPA HSQLDB server	DataNucleus DB4O embedded	OpenJPA HSQLDB server	DataNucleus DB4O embedded	OpenJPA HSQLDB server
