Top of the line MacBook Pro, freshly installed with only Sublime Text and Atom side by side shows a very, very clear performance difference. I have a fetish for clean machines, so it's an "experiment" that repeats itself quite often for me.

Don't get me wrong - I use Atom quite often. However, stating that it does not jave performance issues is just wrong. Period.

Atom needs to do a metric fuckton more work (webengine, remember?) to move the cursor than Sublime, and thus it has severe keystroke lag. Whether you're okay with it or even notice is something entirely different.
