Some of it is out of curiosity and some of it is is I have a shell function wrapping a perl script which does tab completion and I wanted to get a baseline.

My m1 mac is almost 100% faster: 0.21s user 0.13s system 85% cpu 0.399 total

Given the non-difference between my 2020 imac and 2014 imac, I'm wondering if I might have something configured in a way that is slowing things down. Both are running SSD drives but the 2020 machine has a very beefy processor. So that leads me to believe there is some kind of bottleneck on the newer mac. Maybe it's the OS version (Big Sur vs. Monterey). But the m1 and the 2020 imac are running the same OS version and there is a huge difference.

So I'm very curious to know what might explain the similar times between the older mac and the newer one.
