What you reported was more educated guesses than results.
No, these are results.
Why don't you actually _measure_ some hopefully typical Emacs use, and tell us exactly how you got these measurements. Start off saying how you configured your build, followed by calling emacs -Q, with all the other detailed steps needed to duplicate your measurements.
This information is all upthread, but in case you missed it, I'll repeat it here. I built Emacs with its standard configuration options (IOW I just typed "make" in a fresh clone of the repository), on an up-to-date and unloaded Debian bookworm machine. To split the time of make check between compilation and execution, I used the attached patch (which I already sent upthread).
You may have seen that this optimization has no effect without --with-native-compilation. This may explain that.The bootstrap time without native compilation is much shorter in any case.
This is an unrelated question, but no, it is not. With just "make" (IOW without --with-native-compilation) I do not see a significant difference between 10083e788f and 808917b3fc.
