Then look at the response times. Well, we have the same JDK installed. It is running in the exact same computer. Deploying the exact same app. Except the beans are writting using EJB3 annotations in JBoss 5.1.0. But that shouldn't affect the speed of simple string handling methods right? The simple methods to build an xml string in the EJB is taking up to 200-300% longer time. We need a single call to the method to be quick. It is not an option to have it that slow. JBoss 5.1.0 is slowing down all java methods that is running inside it somehow, and we need to figure out how to make that stop. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/526389#526389
