I can also vehemently endorse Andrea Corallo's work on native-comp/libgccjit. The compilation can be finicky so I recommend looking at the AUR script here: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=emacs-git https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=emacs... or this lovely article: https://www.masteringemacs.org/article/speed-up-emacs-libjansson-native-elisp-compilation https://www.masteringemacs.org/article/speed-up-emacs-libjan...
