The Five Whys of Web Font Loading Performance
Originally presented at Performance.now(), The Web Performance Conference on November 8th, 2018 in Amsterdam, Netherlands 🇳🇱.
This was a completely revamped version of my Web Font Loading talk with a brand new theme and new examples. I took the audience through a case study improving the web font loading of the default theme you get when you create a new blog on wordpress.com. It originally loaded five different font files from Google Fonts.
The presentation iterated through a variety of different font loading tools and showed how they affected the performance of the site using real data and results from webpagetest.org.
