The 3.5s dash for attention and other stuff we learnt from RUM

We've seen reports from various companies about how changes in page load time affect conversions. We've also seen user surveys that tell you how quickly users expect pages to load. These are interesting numbers, but we wanted to look at things a little differently. Can we tell how different types of users react to page load times without actually asking them? How do user expectations change over time? How do I decide whether a performance problem is really something I should spend time fixing, or if it's okay to leave it be? How do we collect this data, and what do we do with it before it's clean enough to draw insights from?

In this talk we'll try and answer many of these questions.

And as a bonus, ask us how we reduce our Heisenberg coefficient to a minimum.
