Analyst(s): Ray Valdes


Many Gartner clients struggle to understand what sort of response times website users expect, and how they can optimize the design of their sites to meet these expectations. We provide answers to some of their common questions.

Table Of Contents
  • What do users expect in terms of website performance (i.e., page display speed)?
  • How long should a Web page take to display?
  • What performance thresholds do the top 100 websites define?
  • What is the latency time that we can expect between the Web server and the end user's browser?
  • How can slow-performing sites mitigate latency?
  • What role can Ajax and rich Internet application technologies play in improving response times?
  • What is the role of the user-centered design process with regard to performance?
