You may want to experiment with a "slimmed" configuration where you can reduce the server's memory use by removing services. The ability to modify the configuration of a JBoss server is actually one of its most important features. You can remove features that you don't use to save memory, or CPU resources, or to enhance the security of your installation by reducing complexity and the number of features. But, before you start modifying a profile, you should make a copy of it, so, in the event you make some mistakes in your modifications, you can easily restore the original profile.
