Best of: Understanding Perceived Perfomance #PerceivedPerf

We tend to think of web performance in purely objective terms: seconds to first paint, milliseconds of latency, and so on.  We build apps to be as objectively as speedy as possible and blindly hope that fast feels fast.  Unfortunately, as anyone who's ever waited in line at the DMV can tell you, humans are terrible at judging time.

If we instead shift to address perceived performance directly, we can make our creations feel even faster than they already are.  By exploiting how humans see time, we can build experiences that feel immediate & satisfying.

What we'll cover:

  • Why solely pursuing objective web performance is a flawed paradigm
  • How humans perceive time regarding active and passive phases
  • How to make passive waiting time less apparent
  • Predictive design, the sneaky art of preparing for a user's next action before they take it to reduce or even eliminate perceived waiting time
