Run 'emacs -q' (no add-ons loaded) and it should be a lot faster than VS Code. Which means that a library you loaded is the culprit. Things like Doom Emacs are notorious for unexpected slowness since they're not very well put together and load questionable libraries. In the unlikely case where emacs -q is still slow, use Emacs Mac Port (https://github.com/railwaycat/homebrew-emacsmacport/releases/tag/emacs-29.1-mac-10.0 https://github.com/railwaycat/homebrew-emacsmacport/releases...). This is at least 2x perceivably faster than VS Code on Mac.
