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 973 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 491.5 KB over 26 request(s). Javascript files are 80% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
The HTML itself arrives gzip-compressed.
It runs over HTTP/3, so the assets share a connection instead of opening one each.
90% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
The largest element painted at 1.23 s, inside the 2.5 s Google calls good.
The main thread was blocked for 171 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.

Top issues

Server response time (TTFB)

high impact

The first byte arrived after 973 ms. Of that, 857 ms was the server thinking and 116 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

5 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 381.6 KB 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.

Render-blocking resources

high impact

4 render-blocking resource(s) in the document head (1 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.

Third-party weight

medium impact

2 third-party host(s) serve 441.8 KB of this page. Each one is another DNS lookup, TLS handshake and point of failure you do not control.

Fix: Self-host the libraries you can, drop the tags you cannot justify, and preconnect the ones you keep.
