Knuth's Optimization

ELI5 — The Vibe Check

Donald Knuth said: 'Premature optimization is the root of all evil.' Don't waste time making code fast before you know it's slow. Write it clearly first, measure where it's actually slow, THEN optimize those specific parts. Profile, don't guess.

Real Talk

The famous quote from Donald Knuth (1974): 'We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.' This principle advocates for writing clear, correct code first, then using profiling to identify actual bottlenecks before optimizing.

When You'll Hear This

"Stop micro-optimizing that loop — Knuth would tell you to profile first and find the real bottleneck." / "We followed Knuth's advice: wrote it cleanly, profiled, and found the bottleneck was in the database query, not the code."
