I've made some tests and - I'm not sure where DB is being stored.. I did 
the following:

1. Started repository and checked memory usage of it
2. Added 30 MB of XML files
3. Shut down the repository.
4. Started it again and checked memory usage.

It is quite the same as in point 1.

But that is not the point :) anyone have an idea how to configure 
Jackrabbit to perform like eXist?
