Re: More build times

[Gregory Heytings]

Here is the graph you wanted.

I built Emacs at 500 points, from 2018 to today, on an up-to-date and 
unloaded Debian bookworm computer, and took the average wall clock time of 
10 builds with "make -j20".

The build times are in general constant.  The few commits that change the 
build time significantly, figured by breaks of the red line in the graph, 
are:

obvious sources of bug#30635
d12e5d003d deterioration from 78s to 95s (22%) Daniel Colascione Add portable 
dumper
.......... gradual deterioration from 95s to 108s (14%) from January 2019 to 
February 2021
