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).

Astro what actually works on this platform
Astro ships no JavaScript unless you ask for it, so a slow Astro site is almost always one of two things: islands hydrating when they do not need to, or the HTML being built per request when it could have been built once.
- The HTML is served as a pre-built file straight off the web server — nothing is built per visit, so look at what the page ships rather than at the server.
- A crawler reads about 19,476 characters of text from your HTML — healthy, which is what Astro is good at.
- No CDN detected in front of the site — for a static Astro build that is the cheapest win available.
- Check your client: directives before anything else. client:load hydrates an island immediately and costs the visitor JavaScript on first paint. client:visible defers it until the component scrolls into view and client:idle until the browser is free; most islands want one of those. A page full of client:load is the usual reason an Astro site feels heavy.
- Know whether each route is static or server-rendered. Astro can output a static file, render per request, or mix the two per route. A page with no per-visitor content that is rendered per request pays for it on every visit. Prerender the ones that can be, and let the CDN serve them.
- Use astro:assets for images. It emits modern formats at the sizes actually used and reserves the space so the layout does not shift. Raw <img> tags are usually the largest remaining payload on an otherwise lean Astro site.
- Watch what a shared layout pulls in. An import in a layout is charged to every page that uses it. One heavy component or icon set there outweighs anything you will save on an individual route.

xSpeed is a WordPress plugin, so it can't automate Astro fixes — and that's fine. Every check below links its official guideline, and the machine-readable twin of this report gives an AI everything it needs to plan the work (5 checks name a concrete remediation):
Read the speed report at https://xspeedcache.com/scan/r/xspeedcache-com-d76b28655b.md — it lists every failing check with evidence and the official guideline for the fix. Produce a prioritized fix plan for my Astro site, apply what you can, then re-test by POSTing {"url":"https://xspeedcache.com/"} to https://xspeedcache.com/api/scan and compare the scores.Hosting is half of every score.
Whatever the stack — Astro included, the server behind it sets the floor on TTFB. xCloud — from the team behind xSpeed — hosts any platform (this site's own scanner runs on it), with agent/MCP access built in and bring-your-own-server pricing.
