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 took 579 ms. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
  • The page transfers 612.3 KB over 25 request(s). Images files are 87% of it, so resize and recompress the largest images before anything else.
  • It still answers over HTTP/1; HTTP/2 or 3 would remove most of the per-request connection cost.
  • 52% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
  • The largest element painted at 976 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.003), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 28 ms in total, which is not enough to feel.

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.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 579 ms. Of that, 327 ms was the server thinking and 253 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

0 text response(s) of 10 KB or more are sent uncompressed, and the document itself is compressed. That is 0 B 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.

Render-blocking resources

high impact

3 render-blocking resource(s) in the document head (0 script(s), 3 stylesheet(s)). The page cannot paint until each one arrives.

Fix: Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.

Cache static assets

medium impact

3 asset(s) answer without a Cache-Control max-age, so browsers revalidate them on every visit.

Fix: Version filenames on change and serve them with a long max-age plus immutable. That is what makes a returning visitor fast.
