Talk Description
In typical performance testing talks, we hear about what it is, the tools that can help you, and the critical metrics to consider. However, it's equally important to understand the why. Studies show that users value website performance over design, yet most companies will spend much time making their websites look beautiful. Slow websites irritate us, and if you don’t get the information you need within 10 seconds, you end up feeling dissatisfied. But why does it annoy us?
In this Masterclass, you will take a step back and explore the psychology of waiting and how it relates to web performance. As testers, we must test the system just like our end users. So, it's crucial to understand why page speed matters to deliver a product closer to our users' needs. Apart from the actual page speed, you must also understand that users have subjective perceptions of performance, which can impact your website's speed.

At the end of this Masterclass, you'll have an overview of the different human factors that can affect the performance of your application. Plus, recommendations and tips you can share with your team on making websites faster for both objective and subjective performance measures.

What you’ll learn

By the end of this masterclass, you'll be able to:

  • Recognise the importance behind the psychology of speed and performance
  • Differentiate between the two angles of waiting
  • List various factors that make the wait time seem longer and unenjoyable
  • Outline tips on optimising the psychology of wait time and improving UX
