I've been programming for 35 years now, and I've done a lot of work optimizing programs for speed (an example), and watching others optimize. Two essential techniques are consistently ignored. Nope, it isn't avoiding premature optimization. It isn't replacing bubble sort with quicksort (i.e. algorithmic improvements). It's not what language used, nor is it how good the compiler is. It isn't writing i<<2 instead of i*4.
