I wrote a new blog post about font subsetting and how it can improve #webperf. I've included a few examples and research from the HTTP Archive 💾 . I also created a new tool called "Web Font Analyzer" to analyze fonts on your site. Check it out here - paulcalvano.com/2024-02-16-ide…

I wrote a new tool to help analyze potential third party performance risks on your site. It uses data from WebPageTest™ to group metrics that you can use to estimate if a third party is a performance or failure risk. More details here - paulcalvano.com/2024-09-03-dis…
