And these days, it's up to the compiler to do profiling optimizations, not the programmer. The only optimization really left to programmers now are macro-level... i.e. choosing a O(n log n) algorithm over an O(n^2) algorithm.

Compilers can do a lot, but the coder should look at a profile as well. In one project (Hat random container), when I profiled the code, I found out that it was spending a lot of time in one particular function call (the update_weights function). With this information, I was able to get a good speed boost by moving one locally constructed variable into a class member position.
