Which compiler are you using?

If you're looking for performance, you should use gdc or ldc, as they
have better optimizers. While dmd is the most up-to-date in terms of
language implementation, I've found that the code it generates
consistently performs about 20-30% slower than code generated by gdc
(sometimes even more, depending on what the program does).
