Hello folks, I ran this test with a 7.4Mb, 55 page score, to compare the binaries provided by lilypond.org and the natives ones I (finally) built locally on my 8 Gb RAM Mac Mini. The necessary libraries have been installed using both MacPorts and Homebrew, since not all of them are supplied by a single source.
Both versions are 2.23.12. The speed increase is roughly 20 to 25%, thanks to the avoidance of Intel CPU instructions emulation. I will send the test file privately to anyone interested with pleasure, and you can send me larger files for more tests. A nice day! JM -- First convert the LilyPond file to version 2.23.12.
