Just out of interest, do we tweak the JIT_THRESHOLD somewhere or do we
use the default value?
I don't think we change it from LilyPond, so likely using the default
value.
I did a test with the opposite extremes.
Again, 10 subsequent runs with the score I tested before.
Note that the times are not quite comparable with my last findings,
because my laptop
ran on a different energy saving state.
GUILE_JIT_THRESHOLD=0 (compile each function at first sight)
real 4m8.780s
user 0m0.075s
sys 0m0.167s
GUILE_JIT_THRESHOLD=-1 (disable JIT compilation)
real 4m4.925s
user 0m0.030s
sys 0m0.136s
So either the env variable is not working as intended, or there is only
a very small effect.
At least setting `GUILE_JIT_LOG` does work, but one would have to read
the source
to understand the output.
