We had experienced problem with performance on Jboss 7.1.1.
Now in JBoss 7 version it is impossible to open url via :8080 in order to make thread dump, or see CPU usage. (previously it was very usefull to make)
how it is possible to found bottle necks now in order to find and solve performance problems?
Thank you in advance.
You can use the jmap/jstack and other JDK utilities (jconsole, visualvm) and connect to the JBoss process. The process is a bit different if you can run them on the same host or if you have to use remote access. Googling around should show up the documentation.
