I am not sure if this was just temporary, but I have just used Atom, but its avg energy impact was too high, like 23, which is really not possible, a lot more than a browser (for example Safari: 4). I noticed this after my 4 months 16-GB Mac machine started warming like just a really few times.
Can you tell me what could be the problem? Why Atom consumes so much energy?
Better to use TextWrangler or Notepad++
