See if you can install elisp-benchmarks from GNU ELPA or the web: https://elpa.gnu.org/packages/elisp-benchmarks.html Then you can clearly see if it makes a difference what speed native-compile is set to. You can also try 0 and 1, and report the results here, if you like. I'm on gcc (Debian 10.2.1-6) 10.2.1 20210110 - I think that (too old version of gcc) was the reason Emacs and the computer got nonresponsive when trying `native-comp-speed' at 3. I don't know if it is trivial to install a newer version of gcc from scratch on Debian, maybe I'll try it tonight. -- underground experts united https://dataswamp.org/~incal
