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 388 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 1.76 MB over 26 request(s). Images files are 99% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives zstd-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.
  • The largest element painted at 1.10 s, inside the 2.5 s Google calls good.
  • Layout shift is 0.157 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
  • The main thread was blocked for 22 ms in total, which is not enough to feel.

Fix first: Image delivery and format - 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.

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.

Page weight by type

What the page is made of

Images 9 requests
1.75 MB 99%

Transfer size, compressed as sent. 26 request(s) in total, 1.76 MB across all of them.

Top issues

Image delivery and format

high impact

5 image(s) over 200 KB and 5 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.

Total page weight

high impact

The page transfers 1.76 MB across 26 request(s), with the document itself at 16.2 KB.

Fix: Work through the heaviest assets first: images, then fonts, then third-party scripts.

Third-party weight

medium impact

4 third-party host(s) serve 1.75 MB 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.

Mobile viewport

medium impact

No viewport meta tag, so a phone renders the desktop layout scaled down.

Fix: Add a viewport meta tag with width=device-width and an initial scale of 1.

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
