------------------------------------------- Processor & Memory Performance Bench v4.20 ------------------------------------------- Stop all program before the test. Do not use the computer during the test. The test will run some minutes, please be patient. Total memory required = 4.2 MB. Calibration loops: 8 ------------------------------------------- Comparing different CPU functions: Results are in million instructions per sec. Higher value is faster.
