Now this is really cool! Followed @AndyDavies latest blog post on WebPageTest and @Cloudflare Workers to test the perceived performance difference the `font-display` property has on https://t.co/CcU3PLPTpj. No redeploy to production needed! #webfonts#webperf#perfmatters
We'll be going live this Thursday at 1pm ET for a Q&A with @patmeenan and @mdaoudi on Webpagetest. Tell us what burning questions you have in the comments below.
