Are you sure it isn't a Gawk problem?  Did you look at the gprof
profile I posted, and if so, does everything there look as expected?
Because it could be that these scripts, no matter how inefficient and
badly written, expose some issue with Gawk, which somehow rears its
ugly head on Windows 10.  Until we have eliminated that possibility, I
don't see how we can decide this is off-topic here.

I do agree that the continuing discussion of how to improve the
scripts may have crossed the line of being on-topic here.  But that
wasn't what I was asking about.  The only issue that still bothers me
is the sudden performance regression when the scripts were used on
another version of the same OS.  We don't have any explanation for
that, and in the experiment I conducted (see my report yesterday,
which surprisingly didn't get any responses) I couldn't reproduce the
regression.  Does the lack of responses to that experiment mean we
consider the regression to be some fluke in the OP's environment
unworthy of our attention?  If so, we can indeed stop talking about
the problem here.
