[hibernate-dev] Memory consumption

Hi all, I have today deployed our application for the first time on JBoss 7 with the latest Hibernate and Hibernate Search versions. And I was totally shocked when I saw the memory consumption. I have created two screen shots from the memory dumps. The screen shots are attached to this mail. Please take a look at them. The screen shot names contains version numbers of the used Hibernate and Hibernate Search frameworks. The memory dumps were created for one and the same application version. I can't believe that the latest versions require nearly twice as much memory as the old versions to perform the same tasks. What's happen? Is this a known problem? Do you have any plans to change this situation, e.g. to work on reducing memory consumption? Or maybe you already started to work on this problem? We have been running our application with 768MB for max heap size and serving hundreds of users. And now using the same memory settings I can just deploy the application. :-( Best regards Andrej Golovnin
