Based on my experience, you will, with gdc / ldc. The optimizers in gdc/ldc are much more mature than in dmd; I've compared the disassembly and measured running times with gdc -O3 vs. dmd -O, and gdc consistently produces code that performs 20-30% faster. YMMV, of course, since the exact amount of speed gain depends on what your code does. > Because i use rdmd it takes care of passing everything to dmd.

It shouldn't matter what order the files are. If it does, it sounds like a bug! > There must be a simpler way to pass these files to dmd in the right > order? rdmd does it somehow. > > Any ideas?

Both require some amount of learning to use effectively, though. If all else fails there's always makefiles, but I rather use them only as a last resort. T -- Life is unfair. Ask too much from it, and it may decide you don't deserve what you have now either.
