Where the first byte went

  • Server wait 100 ms 53%

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 188 ms, which is fast: almost all of the wait is the page itself, not the host.
  • The page transfers 4.55 MB over 26 request(s). Images files are 99% 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 892 ms, inside the 2.5 s Google calls good.
  • Layout shift is 0.297 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
  • The main thread was blocked for 196 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.

Page weight by type

What the page is made of

Images 25 requests
4.53 MB 99%

Transfer size, compressed as sent. 26 request(s) in total, 4.55 MB across all of them.

Top issues

Image delivery and format

high impact

10 image(s) over 200 KB and 10 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.

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.

Total page weight

high impact

The page transfers 4.55 MB across 26 request(s), with the document itself at 25.2 KB.

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

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
