Yeah, when it comes to performance-related things, don't bother with DMD. Its optimizer is known to have limitations, and IME consistently produces code that underperforms LDC-generated code by about 20-30%, sometimes even as high as 40%. For performance comparisons, always use GDC/LDC. T -- If you're not part of the solution, you're part of the precipitate.
