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 took 5.46 s. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
  • The page transfers 203.8 KB over 16 request(s). Css files are 55% of it, so split the stylesheet so the first screen does not download the whole site.
  • The HTML itself arrives gzip-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.

Fix first: Server response time (TTFB) - Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

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

Server response time (TTFB)

high impact

The first byte arrived after 5458 ms. Of that, 335 ms was the server thinking and 5123 ms was connection setup. A first byte under 400 ms is what a visitor feels as instant.

Fix: Cut server think time: page cache, query indexes, fewer synchronous calls to third parties inside the request. Connection setup is distance, so a nearer region or a CDN edge helps instead.

Render-blocking resources

high impact

6 render-blocking resource(s) in the document head (1 script(s), 5 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.

Cache static assets

medium impact

6 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.

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
