Hi,
I am doing some performance comparisons between different JPA implementations (Hibernate, OpenJPA and Eclipse). One of the features for the comparison is the space complexity of each JPA implementation. I need some tool with the help of which I can do this kind of testing. Please any help is appreciated.
thanks

The number of entities are almost 45, the number of fields are about 50 and the number of association about 20,,,
I hope that helps

I was suggesting that those numbers give you a guide as to complexity. I don't know that there is a specific formula for JPA.

My question is if there is any way how much space the hibernate will take when the application is run and when the hibernate maps the entities to the application.
