Lab data: Lighthouse 13.5.0 mobile run, graded above · Reproduce this run on PageSpeed Insights ↗
Real visitors (Chrome UX Report)
Not enough Chrome traffic for field data on this page or its site, so only the lab run above is available.
Why is this different from the score in my browser?
This view grades the mobile run. Lighthouse 13.5.0 runs at Google through the PageSpeed Insights API on an emulated mid-range Android with a 4× CPU slowdown and a throttled connection. Chrome DevTools on your own machine, on the Desktop preset, applies almost none of that, and the same page routinely scores 30–50 points higher there. Neither number is wrong — they are different tests.
Mobile is what Google ranks on, so this is the number that affects your
search performance. To reproduce it, open the same run on PageSpeed Insights,
or pass strategy=mobile to the PageSpeed API — it defaults to desktop.
Lighthouse also varies a few points run to run on the same URL. Treat a trend across several scans as the signal, never a single digit.
Lab data: Google PageSpeed Insights (Lighthouse, mobile). Server probes (TTFB, compression, cache, headers) are measured separately from Vilnius, Lithuania (EU).

This is WordPress — the fixes below are one plugin away

- →xSpeed Cache installedFree on wordpress.org — the setup wizard turns most of this report green.
- –MCP signal presentThe scan did not confirm MCP availability. Configure it in xSpeed → MCP Server, then verify authenticated access from an MCP client.
- –xSpeed Hub signalOptional: review Hub configuration and confirm authorized site membership at app.xspeedcache.com.
16 of these checks map to an xSpeed feature. Install the free xSpeed Cache plugin, connect its built-in MCP server, and your AI assistant can apply every fix and re-verify. If your AI already has access to the site (WP-CLI, SSH or hosting MCP), paste this:
My WordPress site digitalwhale.de scored 26/100 on xSpeed Scan (https://xspeedcache.com/scan/r/digitalwhale-de-fab5eb6de6). Install and activate the free xSpeed Cache plugin from wordpress.org/plugins/xspeed, run "wp xspeed mcp connect" and give me the MCP URL to paste into my AI client. Then read the failing checks from https://xspeedcache.com/scan/r/digitalwhale-de-fab5eb6de6.md and apply the fixes: enable page caching, compression, minification and lazy loading, warm the cache, and re-scan at https://xspeedcache.com/scan to confirm the score improved.Hosting is the other half — and 2.0s to first byte says the origin is struggling.
xSpeed makes any host faster, but a cache is only as fast as the server behind a MISS. A TTFB this high usually means underpowered or oversold hosting.
xCloud — managed hosting from the team behind xSpeed — gives the cache an origin tuned for it, with agent/MCP access built in and bring-your-own-server pricing.

TTFB 2.0s measured from Vilnius, Lithuania (EU) (best of 2 requests). This includes the network round trips between us and your origin, not just server time. Google measured your server responding in 20ms from its own network — the gap between the two numbers is distance, not your server.
The server rebuilds the page on every request. A page cache answers in 5–15ms.
