AOT Compilation N/A Tuning Turned off "Hardware Prefetch" in BIOS. Turned off "Adjacent Cache Line Prefetch" in BIOS. Turned off "L1 Data Prefetcher" in BIOS. Turned off "Data Reuse Optimization" in BIOS. Each JVM instance was affinitized to 2 cores of a socket. Using the local security settings console, "lock pages in memory" was enabled for the user running the benchmark. Notes
