A presentation at London Web Performance Meetup in in London, UK by Matt Hobbs

WebPageTest (WPT) is the goto tool when it comes to analysing, and ultimately fixing web performance problems with a website.

Much of the power of WPT comes from its waterfall chart visualisation.

At first sight it can be confusing to understand, but once mastered it will add a whole new dimension to the data that WPT gives you. This in turn will allow you to make improvements to your website that will really benefit your users.

In this talk Matt will to go over some of the basics of the waterfall chart, as well as delving into some of the more advanced topics.

Hopefully giving you a foundation for future exploration of this incredible tool.
