I've noticed Spotlight using a lot of processor time and when I review where it's digging about via sudo fs_usage mdworker mds, I see that most of the time is being spent in /System/Library/ and /Library/ as well as some other places like /opt/ for Homebrew and MacPorts.

I'm curious, has anyone compiled a safe list of paths/folders to exclude from indexing by Spotlight so as to reduce Spotlights indexing load and database size?

I haven't found anything yet, but this script might prove useful to exclude, for example, all node_modules, all .git, all Caches, etc.: https://alexwlchan.net/2021/08/ignore-lots-of-folders-in-spotlight/
