Hibernate production performance

[Abhilash Chander]

Hi All,
I want to implement ORM solution in my application and I am thinking of using Hibernate for the same. But as I am using Apache Tomcat web server I wanted to know what are the memory requirements of Hibernate ? And is Hibernate going to have a major negative effect on the overall performance of the application because of its hunger for memory. Opinions and Suggestions are welcomed.

Thanks
Abhilash

Not sure what the connection between using Tomcat and wanting to know Hibernate memory usage is.

A *major* negative impact? Most likely not, unless you do it wrong. Any ORM solution is going to have memory implications--any time you're moving data from a result set into object instances you're going to use memory.
