Hi, I'm currently conducting some performance-tests on a small web-app I wrote, that is running on JBoss 4.0.5GA. I currently have about 150 concurrent requests, which seems to kill my JBoss server (2x Xeon 1,3GHz, 2 GB RAM). While the test is running I don't get any response from jboss anymore. Why would that be? I already increased the memory for the JVM set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m is there anything else I could configure (like the number of threads or something?) Any hints would be appreciated! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040449#...
