Abstract
Last chapter we coded an automated solution to track and visualize the web performance of URLs over time. We used WebPagetest to generate our metrics, PHP to aggregate and scrub the numbers, and R to create data visualizations from those numbers. We called this project WPTRunner, and we can use it to test the efficacy of future optimizations that we would want to implement and the performance of new features that we will develop.
