“For software developers who take their work seriously, Knuth is the consummate craftsman. Here’s what he has to say about optimization: Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.2 (Emphasis added.)”
