Cloudflare Browser Insights

There’s a lot of info in this graph! At a high level, there are two main types of metrics

• Request-level metrics like TCP connection time, or Request time. These metrics are counted on every page load and are impacted by Internet infrastructure, like the mobile network of your end users, or the speed of your servers.
• Page-level metrics like Page Load Time, which take into account the many requests needed to load a web page, plus the time taken to parse HTML and execute JavaScript.
