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.
