AOT Compilation   Tuning OS The start command was used to affinitize each JVM to a socket. The affinity mask, %CPUS%, was set to the following values: 3F, FC0, 3F000, FC0000. Using the Local Security Settings console, "lock pages in memory" was enabled for the user running the benchmark. Notes The command line options are described at: http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp
