So, to illustrate the idea of using the benchmark at the list below, it might be the Mac mini (Late 2020) with single-core score 1712 and the other Macs of this year have a similar performance. It gives for the iMac 2008 used a single-core score 372 (depending on model), and it took 4–5 minutes to compile the same example. Then 1712/407 = 4.6, and dividing 4 minutes with that gives 53 seconds, and this ignores speedups in lilypond self, but it seems one can get a rough idea of performance this way.

Are there any test sheets with different CPUs and the time they take to output a score that takes a long time to compile? In case this doesn't exist specifically for LilyPond, is there anything equivalent I can use?
