On mac, Instruments (part of xcode) is the app that lets you sample a binary's performance to see where it's spending its time.
- https://developer.apple.com/xcode/features/ has some info about it
- https://developer.apple.com/forums/tags/instruments forum here
similar to perf + flamegraph on linux, I think? Would like to test using it with a Zig binary.
