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 1.16 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 9.19 MB over 26 request(s). Images files are 98% of it, so resize and recompress the largest images before anything else.
It runs over HTTP/3, so the assets share a connection instead of opening one each.
86% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.

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 25 requests

8.97 MB 98%

Transfer size, compressed as sent. 26 request(s) in total, 9.19 MB across all of them.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 1157 ms. Of that, 910 ms was the server thinking and 248 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.

Compress text responses

high impact

0 text response(s) of 10 KB or more are sent uncompressed, and the document itself is compressed. That is 0 B of compressible text.

Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.

Image delivery and format

high impact

5 image(s) over 200 KB and 5 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

8 render-blocking resource(s) in the document head (2 script(s), 6 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 9.19 MB across 26 request(s), with the document itself at 219.6 KB.

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