Compilation time (was: Generate \scaleDurations procedurally) |

Hello,
When trying to compile the complete score of the piece below (88
staves and 120 quarter notes), I noticed it was taking many hours (I
didn't finish the compilation). Trying with shorter versions, I got
the following compilation times:
- 2x quarter notes -> 16.7",
- 4x quarter notes -> 1'17",
- 8x quarter notes -> > 57'47" (!)
Is there anything that could be optimised to reduce the compilation
time? I'm afraid the final version could potentially take many days to
compile.
I'm on a MacBook Air M2 with macOS Ventura 13.4, Lilypond 2.25.5
Thank you for any hint,
Lib
