> CPU and data intensive heavy lifting is rarely done in such programs That's absurd. They aren't as high-performance as C or C++, but Java and C# both have screamingly fast JIT compilers and plenty of high-performance code is written in them. We're not talking about Prolog here. And memory access patterns absolutely makes a huge difference in performance in these languages. Sure, you CAN ignore that kind of stuff if you want to, but good programmers don't.
