emacs empty startup time increased from v 27.1 to 29.0 by factor 3?

[Gregor Zattler]

Hello,

among several runs of

time /usr/bin/emacs-gtk -Q -nw -f save-buffers-kill-emacs

which starts emacs 27.1 as precompiled in debian / Bullseye
and kills it again, a low time values on my laptop are e.g.:

real    0m0,328s
user    0m0,262s
sys     0m0,058s


while for emacs v29.0 the same command line achives low
values like this one:

real    0m1,007s
user    0m0,847s
sys     0m0,154s

The 29.0 version is compiled with native-compilation
support.  Does this explain the differences?


Ciao; Gregor
