I ran an empty perl script with just a single exit command on my newer 2020 intel-based imac running stock 5.34 and ran 100 times with time (repeat 100 {./time.pl})

Got this: 0.39s user 0.28s system 89% cpu 0.743 total

I was surprised to see slightly better results on a 2014 imac running stock 5.30: 0.33s user 0.26s system 81% cpu 0.718 total

So I'm wondering what might be slowing my newer mac down. It's not particularly heavily loaded. And is there anything I can do anything to improve its performance? Thanks.
