I am skeptical that one out of every twenty-five instructions in your program
has to do with checking this boolean.

I would like to ask you to do another test, if you could, since you have both
versions available.

Run your suite maybe 20 times, ten times with the old version, and ten times
with the new version, but interleave them so that you alternate between the two,
and do this via a batch file, so it is all as automatic as possible.

What you should see is slow/fast/slow/fast/slow/fast etc.  What I am a little
afraid you will see is slow/fast/fast/fast/fast/fast etc.
