OK, I just tried it on my office's 2006 mac-mini (Core 2 Duo T7600)
where the above says it has 437 fonts installed (removing the iso10646
constraint brings it up to 614):
% time src/emacs -Q --geometry +10+10 -f view-hello-file --eval '(progn (redisplay t) (sleep-for 2) (kill-emacs))'
src/emacs -Q --geometry +10+10 -f view-hello-file --eval 0.95s user 0.17s system 32% cpu 3.480 total
% time src/emacs -Q --geometry +10+10 --eval '(progn (redisplay t) (sleep-for 2) (kill-emacs))'
src/emacs -Q --geometry +10+10 --eval 0.46s user 0.05s system 19% cpu 2.661 total
%
[ I just used a "sleep-for 2" so I could visually confirm that everything is
indeed displayed. ]
So a "normal" start takes ~0.7s and visiting the hello file brings it to
~1.5s hence adding less than a second.
Just for laughs, I tried it on my 2003-vintage Thinkpad X30 (Pentium III
@ 1.2GHz): the time goes from 1.9s to 5.2s, i.e. visiting the hello file
adds a bit more than 3s (and the above x-list-fonts says 462 on this
system). Definitely not instantaneous but very tolerable.
I expect 500 fonts is not considered large, since I'm not particularly
interested in typography and have installed fairly few fonts above those
that get installed automatically with a "typical" Gnome desktop.
But to justify a delay of more than 10s on a non-ancient system, you'd
need to have at least 10 times as many fonts. Is that really what's
going on, or is there something else at play?
