User development, A new message was posted in the thread "Performance JAS 5.1.0.GA   with Security enabled": http://community.jboss.org/message/531435#531435 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- Sorry, i did not notice that in your first post you already posted the timings from the test (i don't know how i missed that). Let me reproduce this locally. By the way, even though it may not fix the current performance issue, we do have some performance fixes after AS 5.1.0 was released. Please apply our latest EJB3 plugin http://www.jboss.org/ejb3/ejb3plugin.html against 5.1.0 and see if it improves the performance. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/531435#531435
