Dear all,
While working on next year's 'knuth-pdf' package
(https://ctan.org/pkg/knuth-pdf) I have noticed that LuaTeX is the one
PDF engine that revs up the fan of my laptop more than the others.
Running 'time makeall' (see
https://mirrors.ctan.org/web/pwebmac/makeall) gives the following
results (second run each):
$ time makeall -npt xetex
real 1m2,738s
user 1m7,745s
sys 0m8,641s
[$ wc -c *.pdf -> 30355436 total]
$ time makeall -npt pdftex
real 0m53,242s
user 0m53,042s
sys 0m2,140s
[$ wc -c *.pdf -> 40045111 total]
$ time makeall -npt luatex
real 1m15,286s
user 1m13,728s
sys 0m3,615s
[$ wc -c *.pdf -> 44176632 total]
Just an observation.
Best,
Andreas
