Java Language -XXcallProfiling


This option enables the use of call profiling for code optimizations. Profiling records useful runtime statistics specific to the application and can—in many cases—increase performance because JVM can then act on those statistics.

Note: This option is supported with the JRockit JVM R27.3.0 and later version. It may become default in future versions.
