January 28, 2019 — There are many tools that help us understand and improve the state of web performance on our WordPress sites. But it’s not always obvious which tool is right for the job and how to use it. When would I use “field” data from real users? What is my “lab” testing tool trying to tell me? In this workshop, we will examine the landscape of tools at our disposal: WebPageTest, HTTP Archive, Google Analytics, and the Chrome User Experience Report. We will use these tools and real world examples to better understand how slow a website is, what is causing it, and how to fix it.
