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.
- Nothing indicated the HTML came from a cache on this request, which is worth confirming: a static Astro build should be served straight off a CDN.
- 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 (6 checks name a concrete remediation):
Read the speed report at https://xspeedcache.com/scan/r/xspeedcache-com-1bf0a98f69.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.
