Notable among these are clarity, efficiency and simplicity. 細かな効率については、約97%の場合忘れれば良い。なぜなら、時期尚早の最適化は諸悪の根源だからだ。 Translation notes: I just translated "say about" as 約. Good technical design is primarily about balancing several interrelated requirements. This is a classic case of premature optimization. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified. It makes no difference to state that something is half quicker on the off chance that it was at that point quick enough to begin.

What’s more, the time and energy spent on optimization is wasted as our work changes. “Premature optimization is the root of all evil.” ― Donald Ervin Knuth, The Art of Computer Programming, Volume 1: Fundamental Algorithms Yet, we should not pass up our opportunities in that critical 3%. But optimizing our work can distract us from finding and completing the work that matters. "Premature optimization" is a phrase used to describe a situation where a programmer lets performance considerations affect the design of a piece of code. “Premature optimization is the root of all evil” - Donald Knuth. In a few FORTRAN codes I have, the original programmers made use of boolean short circuiting. This can result in a design that is not as clean as it could have been or code that is incorrect, because the code is complicated by the optimization and the programmer is distracted by optimizing.
