I don't work with Windows and have no development environment to build a
64-bits Windows version. And I don't know if the performance improvement
I experienced with the 64-bits Linux variant will have the same effect
with a 64-bits Windows variant. For the Linux variant it is a result of
several factors, ordered in most-influential-first sequence (in my view):
(1) use of an optimizing option of the compiler (-O2, while Kyle used
-O0).
(2) running a 64-bits program in a 64-bits operating system (Kyle's
Linux version is 32-bits).
(3) stripping the executable: making the executable file smaller
(Kyle's version is not stripped).
Maybe items 1 and 3 don't apply to the Windows variant provided by Kyle
and I don't know if item 2 has a big effect under Windows. So the
performance improvement of a 64-bits Windows variant might be not that
significant.
Regards, Rob.
