Can you please stop using Google Chrome in your tests? Because it eats up lots off RAM and CPU for nothing. Not only on the Atom but in general. Normaly you don’t notice it because the system has lots of resources. And on systems where you need to be smart with your resources Chrome will screw it all up.
Make sure you completely remove it from the system.
Please use Microsoft Edge and/or Mozilla Firefox. They are alot more memory effective and will make alot of difference in tests and benchmarks. Like you noticed in this video.
Btw, if you go to the video at 18 minutes you will see that you closed chrome. But it still has 6 or more processes running in the background.
