Oh, it's still slow. Pathologically so in some cases. But, so is VS Code. But, Atom's speed has become manageable in recent versions. I rarely find myself unable to work with a big file in Atom. For code, I rarely see files bigger than a few thousand lines (and never produce files that large myself), and Atom handles them OK (not great, but acceptable, given the other benefits of the tool). VS Code is still better, and of course, vim smokes them both. But, there are trade offs, and Atom has a lot of cool features. I wouldn't use it for really large files, however. It really shows its ass in those cases (as the XML file test here shows).
