Holy moly. I just compiled my local tot for the first time with --with-native-compilation (after installing libgccjit-11-dev) and I am more than amazed at the speed it delivers.

Using desktop.el my regular startup loads lots of buffers from the last sessions and so I am used to slow startup times. Usually I don't care as I do not quit emacs afterwards so this a per-boot (or per-session if something crashes) overhead which amortizes easily.
