Where the first byte went

  • DNS lookup 85 ms 16%

  • Server wait 419 ms 78%

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 540 ms. Everything else waits for that number, so the server is where to start: caching, a slow query, or an overloaded host.
  • The page transfers 2.54 MB over 23 request(s). Images files are 95% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives zstd-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • The largest element painted at 604 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.011), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 8 ms in total, which is not enough to feel.

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.

Browser render

The same URL loaded in a real browser, so these are the readings curl cannot produce. The grade above is still built from the server measurements.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 540 ms. Of that, 419 ms was the server thinking and 122 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.

Image delivery and format

high impact

7 image(s) over 200 KB and 7 large image(s) still served as JPEG or PNG.

Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.

Total page weight

high impact

The page transfers 2.54 MB across 23 request(s), with the document itself at 28.8 KB.

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

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
