Measured on the connection that fetched the HTML. Every other request on the page waits for the end of this bar before it can start.

Every report published here is in this comparison, so it is a reference population of pages tested from one server - not a benchmark of the whole web.

What these numbers mean

  • The first byte arrived in 420 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 674.1 KB over 18 request(s). Images files are 60% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 99% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.

Fix first: Server response time (TTFB) - Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

Read on one shared server, not a visitor's phone: use it to compare pages against each other, not as a promise about every connection. We fix what these tests find.

No screenshot for this report.

The headless browser did not capture this page when the test ran, so only the server measurements are shown.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 420 ms. Of that, 264 ms was the server thinking and 156 ms was connection setup. A first byte under 400 ms is what a visitor feels as instant.

Fix: Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

Compress text responses

high impact

1 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 259.7 KB of compressible text.

Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.

Image delivery and format

high impact

1 image(s) over 200 KB and 1 large image(s) still served as JPEG or PNG.

Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.

Third-party weight

medium impact

1 third-party host(s) serve 666.9 KB of this page. Each one is another DNS lookup, TLS handshake and point of failure you do not control.

Fix: Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.

JavaScript weight

medium impact

1 JavaScript file(s) over 200 KB: bootstrap-local-cloud.e6fe9bbaf52a.js (259.7 KB)

Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.

Each bar is one request's own response time, scaled to the slowest. Assets were fetched in parallel, so the bars overlap in real time rather than stacking. first party third party
