I actually meant process scheduling, but yes assume no other relevant
threads or processes and the architecture/compiled code combination
determines it.

It suggests they are compiled with -O0, as is indeed my current one,
just checked. But is it just these unofficial builds that are -O0?
nt/INSTALL seems to suggest so. Are the builds in
http://ftp.gnu.org/gnu/emacs/windows/ optimized?

I would expect that factor to vary according to type of operation. But
OK, that would make my w32 hardware about 3 times slower for that
particular syntax-ppss operation, since total time is about 6 times
greater, I haven't measured exactly.

Thanks for the tip!
