Which would you rather have: a website that’s fast or a website that’s perceived as fast? The answer is “Both!” The list of performance best practices is long and well known, but there’s been less focus on the user’s perception of speed. In this presentation Steve Souders provides examples of how the perception of speed is completely independent of actual speed, and techniques for leveraging this perception gap to create websites that feel fast.
