When users say a site is slow or fast, it doesn’t correlate with the actual download time, rather it correlates with whether the user was successful in doing their task or not. If successful, the site was ‘fast’ and if not, ‘slow’.

Spool, Jared, "Usability Tools Podcast: Interview-Based Tasks for Usability Testing", podcast, October 1, 2007. Classical usability testing sets up predefined tasks for users to do; but if users do tasks they are interested in, they interact differently with the application.
