AOT Compilation   Tuning 3 processor sets were created using multiple "psrset -c x y" commands where x and y equaled 2,3; 4,5; 6,7. The last JVMwas not run with "psrset -e" in order to run on default processor set. expected_peak_warehouse set to 2. Command line options are described at http://java.sun.com/docs/hotspot/VMOptions.html Notes
