Above the fold time (AFT) measures web page performance by applying
heuristics to a video or filmstrip view of a page loading. It focuses
on what the user sees while at the same time producing consistent
results across multiple runs and different browsers. This presentation
will cover (1) the motivation for AFT, (2) overview the algorithm, and
(3) how to collect AFT on webpagetest.org.
