Without the source codes and the commands used to create and run, it 
is impossible to offer constructive criticism of the results. However a
priori the above does not surprise me. I'll wager ldc2 or gdc will 
beat dmd for CPU-bound code, so as others have said for benchmarking 
use ldc2 or gdc with all optimization on (-O3). If you used gc for Go 
then switch to gccgo (again with -O3) and see a huge performance 
improvement on CPU-bound code.

Java beating C and C++ is fairly normal these days due to the tricks 
you can play with JIT over AOT optimization. Once Java has proper 
support for GPGPU, it will be hard for native code languages to get 
any new converts from JVM.

Put the source up and I and others will try things out.
