www.amazon.fr speed test — 20 Oct 2026

The first byte arrived after 407 ms. Of that, 334 ms was the server thinking and 73 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.

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.

The page transfers 957.2 KB across 26 request(s), with the document itself at 451.6 KB.

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

2 third-party host(s) serve 505.6 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.

The document transfers 451.6 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.
