But even then C++ is basically cost free if used correctly. Of course I am not comparing it with some hypothetical hand optimized assembly, but specifically when considering cache alignment C++ has massive advantage in this area compared to languages like Java. Compared to C there is nothing in C++ that would make cache alignment more difficult by design.
