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 389 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 357.0 KB over 10 request(s), which is lean. Images files are 44% of it, so resize and recompress the largest images before anything else.
  • The HTML itself arrives br-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • The largest element painted at 660 ms, inside the 2.5 s Google calls good.
  • Layout stayed still (CLS 0.003), so nothing jumps under the reader's cursor.
  • The main thread was blocked for 75 ms in total, which is not enough to feel.

Fix first: Image delivery and format - 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.

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

Image delivery and format

medium impact

0 image(s) over 200 KB and 1 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.

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
