- "The order in which the operations shall be performed in every particular case is a very interesting and curious question, on which our space does not permit us fully to enter. In almost every computation a great variety of arrangements for the succession of the processes is possible, and various considerations must influence the selection amongst them for the purposes of a Calculating Engine. One essential object is to choose that arrangement which shall tend to reduce to a minimum the time necessary for completing the calculation." — Ada Byron's notes on the analytical engine 1842.
- "More computing sins are committed in the name of efficiency (without necessarily achieving it) than for any other single reason — including blind stupidity." — W.A. Wulf
- "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. 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" — Donald Knuth
- "Bottlenecks occur in surprising places, so don't try to second guess and put in a speed hack until you have proven that's where the bottleneck is." — Rob Pike
- "The First Rule of Program Optimization: Don't do it. The Second Rule of Program Optimization (for experts only!): Don't do it yet." — Michael A. Jackson

Famous quotes containing the word quotes:
“A great man quotes bravely, and will not draw on his invention when his memory serves him with a word as good. What he quotes, he fills with his own voice and humour, and the whole cyclopedia of his table-talk is presently believed to be his own.”
—Ralph Waldo Emerson (1803–1882)
“Young people of high school age can actually feel themselves changing. Progress is almost tangible. It’s exciting. It stimulates more progress. Nevertheless, growth is not constant and smooth. Erik Erikson quotes an aphorism to describe the formless forming of it. “I ain’t what I ought to be. I ain’t what I’m going to be, but I’m not what I was.””
—Stella Chess (20th century)
“Man is timid and apologetic; he is no longer upright; he dares not say “I think,” “I am,” but quotes some saint or sage.”
—Ralph Waldo Emerson (1803–1882)
