Lab data: Lighthouse 13.4.1 mobile run, graded above · Reproduce this run on PageSpeed Insights ↗
Why is this different from the score in my browser?
This view grades the mobile run. Lighthouse 13.4.1 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. This report predates the desktop-graded headline: only the mobile run was graded. 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).

8 of these checks map to an xSpeed feature. embedpress.com's xSpeed MCP server is live — paste this into Claude (or any MCP client) connected to it:
Connect to my site's xSpeed MCP server, read the failing checks from https://xspeedcache.com/scan/r/embedpress-com-000d6847b7.md, and apply the fixes: enable page caching, compression, minification and lazy loading, warm the cache, then run a benchmark and re-scan at https://xspeedcache.com/scan to confirm the score improved.Hosting is the other half.
xSpeed makes any host faster, but a cache is only as fast as the server behind a MISS.
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.

Time to first byte ≤ 200ms 4/8 pts
TTFB 447ms 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 38ms 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.
