I'm sure. I spent quite a long time between the AMD and an Apple m2 trying.

I did see the same regression as you on the smaller numbers.  I
experimented with the attached which macro'ifies internal_flush() and
pg_noinlines internal_flush_buffer.

Can you try that to see if it gets rid of the regression on the first two tests?
