I thought it might be interesting to look at some compilation numbers.
On "master", a non-native bootstrap build takes:
real 1m9.038s
user 10m7.189s
--with-native-compilation takes:
real 1m50.159s
user 15m56.087s
--with-native-compilation=aot (full ahead-of-time build) takes:
real 3m31.860s
user 55m17.325s
So there's a bigger percentage jump from non-native to native, than
there is from native to AOT. (On this machine; as you can see from the
"user" numbers, the CPU usage tells a somewhat different story.)
Interestingly, the full AOT on "master" on this machine is now faster
than a --with-native-compilation on the emacs-28 branch:
real 4m3.930s
user 36m49.549s
