Hi, I've performed the test on the new version from the trunk. I get: With the CMS Portlet: 15 p/s Without the CMS Portlet: 31p/s Yesterday I was trying to find out where in your code there were the SQL queries logued by hibernate. I was suspecting that they were the bottleneck but the source code is quite big and I had not much success. Anyway I see you have worked on it and now only the cache is hit without actually reaching the DB. I guess that another possible bottleneck are the JTA transactions that are continuously being opened and closed. I would like to try to remove them in order to perform more tests, would you point me to the config or code file where this could be done (if possible)?. I wouldn't mind to lack some functionality during the tests. Regards, Waldemar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3986142#...
