Hi Roy, Thanks a lot for your quick answer. We have performed the tests deploying JBoss 2.4.0, and 2.6.0-DR1 on JBoss AS 4.0.5.GA. What we are wondering is why 2.6 is slower than 2.4. Maybe because of its development state? I'll perform a new test hitting a page without the CMS Portlet as soon as I get to the office on Monday. I'll post my results then.
