When I was trying to port some Java program to D,
I noticed Java is faster than D.
I made a simple bench mark test as follows.
Then, I was shocked with the result.

test results on Win8 64bit (smaller is better)
Java(1.8.0,64bit,server): 0.677
C++(MS vs2013): 2.141
C#(MS vs2013): 2.220
D(DMD 2.067.1): 2.448
D(GDC 4.9.2/2.066): 2.481
Java(1.8.0,32bit,client): 3.060

Does anyone know the magic of Java?

Thanks, Aki.

I have read somewhere (or maybe heard) that Java VM is able to cache and possibly remove/inline dynamic dispatches on the fly. This is a clear win for VM languages over native compiled.
