I often find myself looking at WebPageTest (WPT) waterfall charts, but as I seem to have the memory of a chimpanzee (not a goldfish, that’s a myth), I tend to forget some of the details and what they all mean. So I decided to pull together many bits of information into a single blog post I can refer to at a later date. If you find it useful, or think I’ve forgotten anything, please let me know. If you are interested in learning about the Connection View that sits directly below the Waterfall View, then check out my post ‘How to read a WebPageTest Connection View chart’.
