Thank you for the link. It helped me to find the actual performance difference. It is significant:

I didn’t state it was not relevant, I asked. Glad to see there is an update. My main point stands though, I’d love to see an explanation with posts.

I would love to see a 2022 follow-up from Agner Fog on this. He has work on C++ compilers as recently as 2021 so I'm sure he has recent real world info on the topic.
