Why Java (server VM) is faster than D?

[Justin Whear via Digitalmars-d]

Java being fastest at running Java-style code is not too surprising.  My 
guess is that Java is "hotspot" inlining the calls to `bar`, getting rid 
of the dynamic dispatch overhead.  I think that for real systems D will 
generally beat out Java across the board, but not if the D version is a 
straight up transliteration of the Java--expect Java to be the best at 
running Java code.
