I had asked “Does SWI Prolog run on M1 MacBook Pro under macOS Monterey? If yes, which version?” and mistakenly sent my question only to Jan Wielemaker who answered “As is, the native binaries work on the M1, but slow. If you build SWI-Prolog from source though (or use e.g. Macports) it is impressively fast, almost as fast per core as my AMD 3950X desktop CPU (except that has 32 cores rather than 8).”
Has anybody similar experiences?
