This is shown for various grain sizes, plat-forms, tick frequencies, and OSs. To eliminate such noise, we suggest replacing ticks with an alternative mechanism we call “smart timers”.

The tick interrupt is used to measure time. Therefore a higher tick frequency means time can be measured to a higher resolution. However, a high tick frequency also means that the RTOS kernel will use more CPU time so be less efficient.
