Should we still be optimizing “in the small”?

Question

I was changing my for loop to increment using ++i instead of i++ and got to thinking, is this really necessary anymore? Surely today\'s compilers

Answer 1

Certainly yes, because the compiler needs more resources to optimize not optimized code than to optimize something already optimized. In particular, it causes the computer to consume a little bit more energy, that, despite being small, still causes bad impact on the already hurt nature. This is especially important for open-source code, which is compiled more often than closed source.

Go green, save the planet, optimize yourself
