I generally find that dmd-compiled programs run at about half the speed of those
built with gdc or ldc (the latter seem pretty much equivalent these days, some
programs run faster compiled with one, some with the other). That's running off
latest GitHub source for all compilers.
That's been a fairly consistent speed difference for a long time. And yes, I'm
using 64-bit.
