Detailed performance compilation guide for Emacs, highly actionable but not novel and niche.
Summary
Compiling Emacs from source with -march=native and enabling the native Lisp compiler via libgccjit transforms Lisp packages into machine code, outperforming generic distribution binaries. Dropping legacy X11 for Wayland (using PGTK with gtk3, cairo, harfbuzz) improves rendering and system integration. The guide details dependency installation for Arch, Debian, and generic Linux, and fine-tuning native-comp via native-comp-compiler-options in early-init.el.
