Where the first byte went

  • Server wait 256 ms 65%

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 392 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 279.1 KB over 6 request(s), which is lean. Javascript files are 89% 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.
  • 100% 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 2.06 s, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.026), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 40 ms in total, which is not enough to feel.

Fix first: Third-party weight - Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.

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

Third-party weight

medium impact

1 third-party host(s) serve 278.5 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

1 JavaScript file(s) over 200 KB: 3-render-renderer.js (204.6 KB)

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

Avoid extra redirects

medium impact

2 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
