I routinely see D benchmarks that are 2+ times faster with LDC
compared to DMD.
Have to be careful about benchmarks without looking at why. A few months
ago, a benchmark was posted here purportedly showing that dmd was awful
at integer math. Turns out, the problem was entirely in the long divide
function, not the code generator at all. I rewrote the long divide
helper function, and problem solved.
