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?
