What is premature optimization? If every optimization is labeled as “premature”, a system may fail without any visible performance bottleneck. In my experience it's used more as an excuse for writing sloppy code that is obviously horribly inefficient, or to otherwise rail against making changes that aren't deemed necessary for whatever reason e.g. That's premature optimization. See more. Not really. Premature Optimization is a Real Problem Premature optimization is a problem we developers must guard against. For legacy projects, after proper profiling to identify bottlenecks, rather … Premature optimization would mean that we always try to do performance optimization whenever and wherever we can. To be clear, let's define what we're talking about: premature optimization is the practice of spending development time improving the speed of code before knowing the actual speed profile of that code. No one actually interprets "premature optimization is the root of all evil" as an argument against all optimizations, do they? Knuth’s famous quote about premature optimization was never meant to be a stick to beat people over the head with.

Definition: Premature optimization is when you make code more complex in the name of efficiency without data that it’s actually needed. Premature optimization is often meant to refer to something that makes the code less legible while at the same time attempting to increase performance. ture (prē′mə-tyo͝or′, -to͝or′, -cho͝or′) adj.
