Faster is better
By Kristoffer Bohmann, Bohmann Usability
Tom Farrell: When user-testing sites for download speeds, try and allow users to give up or look elsewhere for information. Make the test as open as possible rather than forcing users to follow one specific route to information.
I don't think usability professionals need to test response times in every test session. Still, the issue needs to be on the checklist when conducting user tests to make sure this doesn't make users less willing to use the site.
