Tuning |
- Turned off "Hardware Prefetch" in BIOS.
- Turned off "Adjacent Cache Line Prefetch" in BIOS.
- Each JVM instance was affinitized to a socket.
- Using the local security settings console, "lock pages in memory" was enabled for the user running the benchmark.
|
Notes |
- input.expected_peak_warehouse is set to 20, because Runtime.getRuntime.availableProcessors() doesn't return number of processors in the system but returns number of processors in the group which the process belongs to on Windows 2008 R2.
- Hitachi Compute Blade 2000 and HITACHI BladeSymphony BS2000 are electronically equivalent. The result have been measured on a HITACHI BladeSymphony BS2000.
- Command line options are described at: http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html
