An engineer identifies &ldquo;the application is slow,&rdquo; forms a hypothesis based on code familiarity, and makes changes based on intuition. Sometimes it works. More often, the actual bottleneck was elsewhere and the optimized code is now more complex with no performance benefit.</p> <p>The methodology matters: <strong>measure, identify the bottleneck, optimize, measure again</strong>. In that order. Not &ldquo;optimize the thing that looks suspicious, then measure.&rdquo;</p>
