I agree, in many D programs I have found that avoiding memory allocations can speed up the code 5-15 times. You can see the last time I have seen that in this thread:
http://groups.google.com/group/comp.lang.python/browse_thread/thread/e291275df01756c6#

But Java HotSpot shows that a good GC can make fast enough many programs that allocate memory often (but they often need 4-10 times more RAM).
