Well, this is kind of disappointing on my end. I attach the full result of a three-way comparison between `main` at the time of Serhiy's last merge (3f8b23f8ddab75d9b77a3997d54e663187e12cc8) with GH-27986 (20e3149c175a24466c7d1c352f8ff2c11effc489) and GH-28176 (cffa90a8b0057d7e7456571045f2fb7b9ceb426f). The gist is this:


Geometric mean 
==============

20e3149c175a24466c7d1c352f8ff2c11effc489-2: 1.01x slower
cffa90a8b0057d7e7456571045f2fb7b9ceb426f-2: 1.01x slower


At least on my Macbook Pro, all PGO builds, looks like the status quo is on average faster than any of the candidate PRs.
