Where the first byte went

  • DNS lookup 79 ms 5%
  • TCP connect 232 ms 15%
  • Server wait 1.26 s 80%

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 1.57 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 1.07 MB over 26 request(s). Images files are 67% of it, so resize and recompress the largest images before anything else.
  • 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.

Page weight by type

What the page is made of

Images 14 requests
738.9 KB 67%
Javascript 11 requests
254.1 KB 23%

Transfer size, compressed as sent. 26 request(s) in total, 1.07 MB across all of them.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 1573 ms. Of that, 1262 ms was the server thinking and 311 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

3 render-blocking resource(s) in the document head (0 script(s), 3 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.

Image delivery and format

medium impact

0 image(s) over 200 KB and 4 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

medium impact

The page transfers 1.07 MB across 26 request(s), with the document itself at 107.7 KB.

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

HTML document size

medium impact

The document transfers 107.7 KB. A bloated document delays every other request, because nothing else can start until it is parsed.

Fix: Paginate long listings, move repeated markup into a template, and stop inlining large data URIs into the HTML.

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
