Hello, is there anyone having experience on Jboss tuning on Amazon EC2? I tried some different configurations, on a m1.large instance without impressive results compared to a traditional server. Following are my JAVA_OPTS -Xms5120M -Xmx5120M -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -d64 -XX:PermSize=128m -XX:MaxPermSize=256m -Xss256k" Matteo View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4225380#...
