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.

How this page compares

Page weightheavier than 64% of 4,999 pages tested here1.04 MB against a median of 650.3 KB

Requestssends more requests than 100% of 4,999 pages tested here26 against a median of 26

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 1.00 s. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
  • The page transfers 1.04 MB over 26 request(s). Images files are 82% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives br-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 95% 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 1.26 s, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.019), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 123 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.

Page weight by type

What the page is made of

Images 10 requests

Transfer size, compressed as sent. 26 request(s) in total, 1.04 MB across all of them.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 1001 ms. Of that, 891 ms was the server thinking and 110 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.

Image delivery and format

high impact

3 image(s) over 200 KB and 0 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

36 render-blocking resource(s) in the document head (0 script(s), 36 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

medium impact

The page transfers 1.04 MB across 26 request(s), with the document itself at 54.5 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 1,011.0 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.

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
