Measure real-world loading performance — TTFB, DNS, SSL handshake, total load time, and Google PageSpeed scores for both mobile and desktop.
We run 3 consecutive requests and average the results for accuracy. Google PageSpeed scores load in parallel.
Three separate HTTP requests are made from our server to your URL and the timing values are averaged for accuracy.
Time to resolve the domain name to an IP address via your authoritative DNS servers.
Time to complete the TCP handshake and negotiate an SSL/TLS session with the server.
Time from sending the request until the first byte of the response is received — a key server performance indicator.
Google Lighthouse scores for both mobile and desktop are fetched in parallel via the PageSpeed Insights API.
