The next-to-last column is with -jTO-THE-MAX, and the last column is with -j1. I’m impressed! The M1 is able to build Emacs almost as fast as my AMD machine… which is a lot bigger. Of course, on Debian I’m using gcc and on Macos I’m using clang, so it’s an apples-to-some-different-brand-of-apples comparison. It’s even more impressive how much faster this laptop is compared to the Apple laptop from… 2019? Yeah. It’s more than twice as fast! And doesn’t have a fan! The old Apple laptop would sound like a VAX in a hurricane while building Emacs!
