“Every 250 milliseconds, you have an opportunity to switch attention,” said Ian Fiebelkorn, Really makes you rethink the speed of website load time. I know there is a ton of research around site abandonment after x seconds (ms in some cases) but I’ve tended to think drop rates were because the time spent was the upper bound of what that user would spend of “continuous” attention. Reading this article it makes me think that if the site takes 4 seconds to load, the user had about 16 opportunities to go do something else. While the abandonment outcomes are what they are, the cause seems to be very different than what I had always thought.
