I noticed today that when changing SIP mode (either enabling or disabling), upon reboot my macOS Monterey CPU usage is heavily consumed by a series of oahd and oahd-helper processes. Researching reveals (see eclecticlight.co and ProjectChampollion GitHub ) this to be related to Rosetta2/AOT but there isn't much detail about what it's doing or how to tame it. If left alone, eventually things settle down after about ***17 minutes*** of churning. Here are some screenshots from my M1 Mac Mini system, running 12.5 as of this writing: How can I manage this better?
