I have Perl on a Apple M1 Max Mac laptop (2021) and a Core i9 Mac laptop (2018). I assumed Perl compiled for arm64 would run much faster than Perl for x86_64.

With regex, it doesn't seem to be the case. The one-liner I used was time perl -e '$n = shift; $na = "a" x $n; print $na =~ /(a?){$n}a{$n}/' X where X ranges over 5,10,15,20,24,30 etc.
