Profiling an application for the Play platform (2.0.2) through VisualVM

I am having serious problems with my game! Application performance. I already tried to change the server and database, but the slowness persists.

Using Firebug to measure my HTTP requests, I found out that it takes about 20 seconds to start responding.

So, my last hope is to use VisualVM to profile my application and find its bottle neck. But I do not know the correct way to pass some arguments, such as "-Dcom.sun.management.jmxremote", without messing up the global variable JAVA_OPTS.

Thanks again!
