does Hibernates stuff have to consume so much memory?

i have developed JSF web application that uses Hibernate.
server machine is strong so i dont care about memory;)

now i must create its equivalent as desktop SWT app.
obviously i want to reuse Hibernate logic from web app.

but my desktop app consumes too much ram.

before that code my app consumes 20MB ram:

Code:

sessionFactory = new Configuration().configure(doc).buildSessionFactory();

and after it app consumes 35MB ram.
(that code maps abut 40 classes and about 60 collections)

doest it have to be so?
can i reduce memory consumction?
scale of my desktop app data is 100 smaller that server data so
i dont need any performance tuning - just low memoty consumction:)

cheers

It is weird. I have about 400 classes in my app and hibernate consumes about 10 Mo.
The best way to see who consumes your memory is to use a profiler. There is a free plugin for eclipse which does that (eclipsecolorer).
You can also grab the ea version of yourkit, for me it's the best profiler and very easy to install and to use. You'll then be able to see if it is hibernate which consumes your memory and why
