Website Response Times

Users really care about speed in interaction design...A snappy user experience beats a glamorous one, for the simple reason that people engage more with a site when they can move freely and focus on the content instead of on their endless wait.

  • 0.1 seconds gives the feeling of instantaneous response. This level of responsiveness is essential to support the feeling of direct manipulation.
  • 1 second keeps the user's flow of thought seamless.
  • 10 seconds keeps the user's attention. A 10-second delay will often make users leave a site immediately.
