  • Server wait 121 ms 62%

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 server answered in 194 ms, which is fast: almost all of the wait is the page itself, not the host.
  • The page transfers 226 B over 2 request(s), which is lean.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.

Fix first: Avoid extra redirects - 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.

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.

Top issues

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.

Mobile viewport

medium impact

No viewport meta tag, so a phone renders the desktop layout scaled down.

Fix: Add a viewport meta tag with width=device-width and an initial scale of 1.

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.

Waterfall

216 ms

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
