Man Emacs Is Slow

I have tried vs code recently after a long while. I opened up one of my react projects, instantly blown away by the speed of autocompletion and navigation. Even typing is faster than in emacs. I am using doom-emacs with minimal tweaks right now, and the typing feels sluggish overtime on both source code files and org-mode files. Restart emacs helps sometimes, but even with fresh instance, it still feels a little bit slower than vs code. Which makes vs code feels more like a native mac app and emacs an electron bloatware. That's a shame, I am still an emacs user, but it makes me seriously considering switching, maybe just for JavaScript/TypeScript projects.
