Disables qualifications compilation. By default, the JVM compiles the tactic being a background job, operating the method in interpreter method right until the track record compilation is concluded.

By default, this option is disabled and no optimization for NUMA is designed. The option is out there only once the parallel garbage collector is utilised (-XX:+UseParallelGC).
