Here are some timings off a reasonably sized carol that generates
seven MIDI files and three PDFs. Old and new versions alternate
(2.18.2 and 2.19.42).
# echo 3 > /proc/sys/vm/drop_caches
real 0m33.921s
user 0m20.040s
sys 0m0.716s
real 0m28.471s
user 0m17.696s
sys 0m0.756s
real 0m20.586s
user 0m19.832s
sys 0m0.556s
real 0m18.838s
user 0m17.600s
sys 0m0.744s
real 0m20.535s
user 0m19.800s
sys 0m0.596s
real 0m18.677s
user 0m17.456s
sys 0m0.844s
So the new version wins by about two seconds.
Note the difference that caching the program makes. You've got to run
a program twice (at least) to get a realistic time.
I always put all the structure of my scores in \score;
ie I don't write variable = \new ...
so I have no comparative data. However, if you try doing
this, remember again to run both versions twice or you may
only be measuring the efficiency of the operating system.
Cheers,
David.
