I have seen people many times mention that Java is in general orders of 
magnitude slower than D, no matter what kind of algorithms you run on 
both environments. This is because of the VM - nothing on a VM can run 
faster than native code, they say. If you decide to hide the bad results 
(for D), it will only reinforce the misinformation. I personally use a 
lot of heap memory allocation in my work, and so far Java has not only 
been safer (and provides decent stack traces and no compiler bugs), but 
also faster - each time.
