title: Memory overhead of neo4j
body: <p>What is the disk-memory overhead of neo4j? At jqassistant I analyse 5 MB of Sources and the compiled jar which includes everything is about 50 MB great. The database-directory is about 500 MB. In other words storing the structure information of an application (not the code himself) need 100 or 10 times more space. Is this a usual relation? </p>
