AOT Compilation   Tuning Lock pages in memory set for the user running the benchmark Windows Power Profile set to High Performance. Used start /node /affinity to bind each JVM instance to 4 cores. Notes Primary cache architecture for the processor is 512 KB I cache on chip per chip with 64 KB shared per 2 cores, and 16 KB D cache on chip per core.
