    I realised that the default behaviour for cpu 0 to 3 on the VOXL2 is to run at a higher frequency (and utilisation) than cpu 4 to 7

    This happens even for a compute intensive process

    Would it help to limit my process to cpu 4 to 7 as such?

    Or should I stick to the default, using all available cores?

      @kerct the higher number cores are larger and more powerful, and they generate more heat. So, the kernel is intelligently biased towards keeping the chip from overheating

        @Moderator oh I see, so to reduce overheating would it be recommended to use the default settings instead of limiting my process to cpu 4 to 7?
