AOT Compilation   Tuning Operating system tunings Turned off "Hardware Prefetch" in BIOS. Turned off "Adjacent Sector Prefetch" in BIOS. Turned off "DCU Streamer Prefetch" in BIOS. Turned off "DCU IP Prefetch" in BIOS. Turned off "Data Reuse Optimization" in BIOS. "Lock pages in memory" enabled for benchmark user. Each JVM instance was affinitized to two cores of a processor chip. Notes Command line options are described at: http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp
