The caveat here is that these results are typical for _number-crunching_ code. 
If the dominant factor in your program's speed is e.g. console output, you'll 
find the differences between the compilers much less noticeable.  For example: I 
have a piece of code that implements a Monte Carlo simulation and prints an 
update of its status at each time step -- with -O -release -inline flags, this 
runs in about 23s with gdmd, 25 with ldmd2 and 28 with dmd.

If I remove the writef statements, leaving just the number-crunching part, it 
runs in about 4s with gdmd, 7s with ldmd2 and 14s (!) with dmd.
