This is what I found when using the InMemPersistenceManager:
My repository contains < 65k nodes and < 500k properties (no binary content). When I exported the content to an XML file, it was about 15MB. When I imported the data into the repository my webapp climbs to 800MB of memory (of course some of that is being used by tomcat and spring managed beans, but that would be far less than even 75MB) Is this normal??? -Jared
