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 317 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 3.36 MB over 26 request(s). Javascript files are 90% 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.
  • The largest element painted at 876 ms, inside the 2.5 s Google calls good.
  • Layout shift is 0.196 (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 144 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.

Top issues

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

13 render-blocking resource(s) in the document head (3 script(s), 10 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 3.36 MB across 26 request(s), with the document itself at 18.1 KB.

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

Third-party weight

medium impact

3 third-party host(s) serve 345.1 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

2 JavaScript file(s) over 200 KB: aa29d35.js (1.33 MB), a205596.modern.js (1.32 MB)

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
