Slow performance compared to C++, ideas?

[finalpatch]

Hi FeepingCreature,

Thanks for the tip, getting rid of the array constructor helped a 
lot, Runtime is down from 800+ms to 583ms (with LDC, still cannot 
match C++ though). Maybe I should get rid of all arrays and use 
hardcoded x,y,z member variables instead, or use tuples.
