Hi Ingo,
I will watch this during the experiments. I have been using klog application to dump relayfs data. I did run powertop and top as well, I will bind them to certain CPUs and isolate their impact.
I believe the margin of error would be less since all the measurement tasks sleep for long duration.
Thanks, Vaidy
