- `emacs` enables native compilation which means:
|
||||
- emacs packages from nixpkgs, builtin or not, will do native compilation ahead of time so you can enjoy the benefit of native compilation without compiling them on you machine;
|
||||
- emacs packages from somewhere else, e.g. `package-install`, will do asynchronously deferred native compilation. If you do not want this, maybe to avoid CPU consumption for compilation, you can use `(setq native-comp-deferred-compilation nil)` to disable it while still enjoy the benefit of native compilation for packages from nixpkgs.
