Lab data: Lighthouse 13.5.0 desktop 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?
The graded score is the desktop run. Lighthouse 13.5.0 runs at Google through the PageSpeed Insights API on a desktop profile with no CPU or network throttling — close to what Chrome DevTools on a laptop, GTmetrix's default test and the PageSpeed API (which defaults to desktop) all measure, so this is the number you should be able to reproduce: run it yourself on PageSpeed Insights.
Google ranks on mobile. That run happens too, on an emulated mid-range Android with a 4× CPU slowdown and a throttled connection, and the same page routinely scores 30–50 points lower there. Neither number is wrong — they are different tests.
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, desktop). Server probes (TTFB, compression, cache, headers) are measured separately from Vilnius, Lithuania (EU).

7 of these checks map to an xSpeed feature. speedlocksmith.com's report indicates that xSpeed MCP is available. This scan did not verify client credentials; if your client is configured and authenticated, use this prompt:
If you are authenticated to my site's xSpeed MCP server, read the failing checks from https://xspeedcache.com/scan/r/speedlocksmith-com-cc98125dfc.md, 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 — and 691ms 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 691ms 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 418ms 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.
