Your curiosity made me curious about this, so ran a little test of my 
own. To compile tango (user library and runtime library) with dmd on my 
laptop:

4.95s user 1.12s system 73% cpu 8.235 total

% wc -l `find tango -name \*.d` | tail -n1
   341330 total

So 340k lines of D compiled with dmd compiles in less time than 120k LoC 
with Go :D

I then noticed this option with tango build tool...

         [-q]                    quick execution

4.85s user 1.18s system 87% cpu 6.937 total

Even faster :)
