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.
