How fast does your server respond? Enter an address — we measure DNS, connection setup, TLS handshake and, above all, time to first byte, plus total time and HTML size. With a speed score, right in your browser.
Your homepage's server response time: DNS resolution, TCP connection, TLS handshake and, most importantly, time to first byte (TTFB) — how long the server takes until the first byte arrives. Plus total time and the size of the served HTML.
Rule of thumb: under 200 ms is excellent, under 500 ms solid, over 1 second clearly too slow. A high TTFB delays everything else — it's the starting gun for page rendering.
PageSpeed and Lighthouse measure user-experience metrics in the browser (LCP, CLS, INP) — how the page feels on a device. This test measures server response time (TTFB), the share your hosting and backend deliver. The two complement each other.
Common causes: slow or oversubscribed hosting, missing caching (page/object cache), heavy or too many plugins, inefficient database queries, or a distant server location. That's exactly what we look at in the audit.
The biggest levers: good hosting, a page cache, fewer and leaner plugins, optimized images, HTTP/2 or /3 and a CDN. In the system audit we measure and prioritize the quick wins.
No. We fetch the entered URL once server-side and show the measurements. Nothing is logged or stored.
