Method perf.cpu

---

Overload

Executes some code in loop for the specified amount of time. It should make CPU to run at full speed.

public static void cpu(int timeMilliseconds = 200)

Parameters

timeMilliseconds  (int) How long to speed up CPU, milliseconds. The minimal required time probably is about 100 ms, but depends on CPU.

Remarks

Code speed measurements often are misleading because of variable CPU speed. Most CPU don't run at full speed when not actively used.

You can make CPU speed constant in Control Panel > Power Options > ... Advanced > Processor power management > Minimum or maximum power state. There are programs that show current CPU speed. For example HWMonitor.
