Actually, that was part of my question. I am not sure that it is a
regression. I was soliciting your opinion on 2 issues: (1) is it (in
principle) a regression, (2) why the difference?
I'll try to work out some code that can actually be executed, so it
can be benchmarked, but I was hoping that someone better acquainted
with instruction costs could estimate it from first principles.
Cheers,
