www.zdfheute.de speed test — 20 Oct 2026

The first byte arrived after 668 ms. Of that, 445 ms was the server thinking and 222 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.

3 image(s) over 200 KB and 0 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.

11 render-blocking resource(s) in the document head (1 script(s), 10 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 3.35 MB across 26 request(s), with the document itself at 191.0 KB.

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

The document transfers 191.0 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.
