WPTRunner—Automated Performance Monitoring and Visualization with WebPagetest

  • Tom Barker


The last chapter laid a good amount of ground work that we will be building upon throughout the rest of the book. We looked at how to generate waterfall charts with Firebug and YSlow, and use them as debugging tools. We explored some of the extensive features and functionality of WebPagetest. We talked about the concept of minifying JavaScript and ran a multivariate test to compare the results of several minifying tools. We closed the chapter by learning about R and writing a script to visualize the results of our multivariate test.
