WebPageTest now uses Chrome's new `renderBlocking` indicator to signal if a resource blocks display of the page, making it easier to zero in on one of the most common perf bottlenecks. Wrote a post about the new indicator and what we're doing with it. blog.webpagetest.org/posts/new-rend…

I am currently trying to add charts to my #cwv Optimizer, to track the CWVs over time. Unfortunately, the charts are getting out of sync and I couldn't find a way to solve this issue so far. Any help is appreciated: stackoverflow.com/q/69850633/173…
