 REM If you have a big server and lots of memory, you could experiment for example with
 REM java -server -Xmx1536m -Xms1024m -Xmn512m -XX:PermSize=256m -XX:SurvivorRatio=8 -Xnoclassgc -XX:+AggressiveOpts
+REM If you are having troubles on server shutdown (saving data),
+REM add this to startup paramethers: -Djava.util.logging.manager=net.sf.l2j.L2LogManager. Example:
+REM java -Djava.util.logging.manager=net.sf.l2j.util.L2LogManager -Xmx1024m -cp ./../libs/*;l2jserver.jar net.sf.l2j.gameserver.GameServer
