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 220 ms. That is workable, and the cheapest win left is caching or a warmer connection.
The page transfers 160.5 KB over 26 request(s).
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 1.17 s, inside the 2.5 s Google calls good.
Layout stayed still (CLS 0.001), so nothing jumps under the reader's cursor.
The main thread was blocked for 142 ms in total, which is not enough to feel.

Fix first: Render-blocking resources - 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.

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

Render-blocking resources

high impact

6 render-blocking resource(s) in the document head (4 script(s), 2 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.

HTML document size

medium impact

The document transfers 124.3 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.

Avoid extra redirects

medium impact

1 redirect hop(s) before the page load started, each one a full round trip before the first byte.

Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.
