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 475 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 417.1 KB over 25 request(s). Javascript files are 67% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
  • The HTML itself arrives br-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 56% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
  • The largest element took 2.92 s to paint, past the 2.5 s threshold: usually a hero image that is too big or a render-blocking script in front of it.
  • Layout shift is 0.382 (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 84 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 475 ms. Of that, 341 ms was the server thinking and 134 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.

Render-blocking resources

high impact

10 render-blocking resource(s) in the document head (8 script(s), 2 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.

Avoid extra redirects

medium impact

1 redirect hop(s) before the page load started, each one a full round trip before the first byte.

Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.

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
