HTTPS Requests
The percent of all requests in the crawl whose URLs are prefixed withhttps.
TCP Connections Per Page
The number of TCP connections per page.
HTTP/2 Requests
The percent of all requests in the crawl using HTTP/2. Note that servers supporting HTTP/2 and HTTP/3 may use HTTP/2 initially due to the way the HTTP Archive starts with a fresh Chrome instance each time, but may use HTTP/3 on subsequent requests.
HTTP/3 Support
The percent of all requests in the crawl which support HTTP/3. Note that, due to the way the HTTP Archive starts with a fresh Chrome instance each time, HTTP/3 will often not be used for initial connections until the browser is aware the server supports HTTP/3, which is why we measure support, rather than actual usage like we do for HTTP/2.
Font Display
The percent of pages that avoid the flash of invisible text (FOIT) during web font loading by using thefont-display CSS property. This metric is measured byLighthouse.
