Quoting "D. Hageman" [email protected]:
That place is after all the functionality you want in a release is implemented and working properly. Then you go back and look for ways to make it faster. People who start optimizing too soon usually spend way too much time getting 2 cycles out of a loop and not enough on the big picture.
Indeed, the software "engineering" literature speaks about the evils "premature optimization".
