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 239 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 1.87 MB over 26 request(s). Javascript files are 91% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 96% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.

Fix first: Render-blocking resources - 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.

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.

No screenshot for this report.

The headless browser did not capture this page when the test ran, so only the server measurements are shown.

Page weight by type

What the page is made of

Javascript 23 requests
1.70 MB 91%
Css 2 requests
100.6 KB 5%

Transfer size, compressed as sent. 26 request(s) in total, 1.87 MB across all of them.

Top issues

Render-blocking resources

high impact

17 render-blocking resource(s) in the document head (1 script(s), 16 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 1.87 MB across 26 request(s), with the document itself at 75.5 KB.

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

Cache static assets

medium impact

1 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.

Third-party weight

medium impact

4 third-party host(s) serve 1.80 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.

JavaScript weight

medium impact

2 JavaScript file(s) over 200 KB: 8785-f29896b3.js (930.4 KB), 9754-72f1477f.js (381.3 KB)

Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.
