You’re maybe trolling. But what exactly is slow? Or are you a superhuman typing 400 words a minute? Emacs have never crashed on me (I use it daily) and there are things you just can’t speed up. Multithreading just sidesteps the problem while introducing its own can of worms. The current async facilities are fine by me (I don’t use any auto* things, so YMMV).
