Windows.
My main question is now *WHY* D is slower than C++ in this
program? The code is identical (even the same C functions) in the
performance-critical parts, I'm using the "same" compiler backend
(gdc/g++), and D was supposed to a fast compilable language. Yet
it is up to 50% slower.
What is D doing more than C++ in this program, that accounts for
the lost CPU cycles? Or what prevents the D program to be
optimized to the C++ level? The D front-end?
