AOT Compilation   Tuning Operating system tunings Turned off "Hardware Prefetcher" in BIOS. Turned off "Adjacent Cache Line Prefetch" in BIOS. "Lock pages in memory" enabled for benchmark user. Each JVM instance was affinitized to four logical cores of a chip. Notes Command line options are described at: http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp
