We need like a native compile FAQ to answer more basic questions, in a simple way. 1. When does it happen to an individual file without you doing anything? 2. How do you explicitely native compile stuff, from a Makefile as well as from Emacs? 3. How do you load it? 4. How much faster is it than byte-compiled code? Is it around 7% as the test say? Why is it still so much slower than SBCL which is 78 875% faster? Is it because Elisp has dynamic typing and the compiler also lacks optimizations that, perhaps, will come in time? 5. (And so on.) I can answer question 2, see these files: https://dataswamp.org/~incal/emacs-init/native.el https://dataswamp.org/~incal/emacs-init/Makefile I can also answer 3: In each file f, do (provide 'f) last, then `native-compile' it, then do (load "f"). -- underground experts united https://dataswamp.org/~incal
