Lightning talk about Perceived Performance
Real user performance - when does the user think a website is slow?
My 7min speech at webtuesday explains what perceived performance is - with the progress bar example. Then talks about the social web - how fast writes should be visible to the various users (me vs. friends vs. strangers). At last show some stuff we at local.ch do to measure perceived render time.
Slide showing the social web metric

Movie from the speech
Thanks to Hugo and Corsin for recording the session.
