Someone needs to fix a memory leak here.

Atom was famously slow. Even among people using it and championing it.

VSCode totally wowed people not just because it was faster, but because it was essentially the first «real» Electron-app which proved Electron-apps could have near native performance.

You got this part 100% backwards.

> proved Electron-apps could have near native performance

I don't think that's true at all. Try running Zed or Sublime.
