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 weightlighter than 51% of 4,999 pages tested here621.6 KB against a median of 650.5 KB

Requestssends fewer requests than 74% of 4,999 pages tested here25 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 arrived in 251 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 621.6 KB over 25 request(s). Fonts files are 56% of it, so subset the fonts and stop preloading the weights you do not render.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 57% 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 820 ms, inside the 2.5 s Google calls good.
  • The main thread was blocked for 191 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

2 third-party host(s) serve 351.3 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.

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.

Strict-Transport-Security

low impact

HSTS is not set, so the first visit on a hostile network can still be downgraded to HTTP.

Fix: Send Strict-Transport-Security with a max-age of at least six months. Add includeSubDomains once every subdomain is HTTPS.

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
