Thanks #Cloudflare @CloudflareDev ! 🙏
I don't see much difference in #WebPageTest though, the site is already pretty fast… 😅
Today: we finaly have a Pro account on WebPageTest so we'll be able to use all Opportunities & Experiments! 🥳
Also today, in WebPageTest header: "Notice: WebPageTest's user account services are currently experiencing issues." 😭
Introducing Opportunities & Experiments: Taking the Guesswork out of Performance
The WebPageTest team has been working on improving the platform since Catchpoint acquired them, and now they're releasing awesome new features to help better test performance and try actual improvements! 😍
Why is #Dareboost reporting "7 resources has a non-consistent extension with its actual content" in this report where #Cloudinary images were proxified through #Netlify, but not on this one where they're not… 🤷♂️
TIL: #Cloudflare doesn't support the Vary HTTP header, which means the origin server can't do any content negotiation, for example send WebP or AVIF for a JPEG request…

#Fastly supports it, just saying… 😅
Performant A/B Testing with Cloudflare Workers
The problem with the current A/B testing tools is they construct the test on the client. They block rendering until they can determine which experiment group the current user should be in, and then they update the DOM based on that experiment’s parameters. On slow connections or low-end devices, this can mean users are staring at a blank screen for seconds waiting for network requests to finish before rendering can even start.
