The different D compilers available don't generate numeric code of the same quality, depending on the algorithms and data structures used. I have found in one of my projects that LDC produces code that is up to 5x or even 10x faster than DMD (though the average difference is less spectacular).
If you use the 64 bit model, dmd will use SIMD instructions for float and double, which are much faster.
