# Website Speed Report, xspeedcache.com

> **What this document is.** A point-in-time speed audit of https://xspeedcache.com/scan/r/drpenfrance-com-3090c25a5c,
> produced by xSpeed Scan (https://xspeedcache.com/scan). Evidence comes from two sources:
> server probes run from xspeedcache.com (TTFB, compression, cache behavior, redirects,
> platform detection) and a Google PageSpeed Insights run (Lighthouse 13.4.1, desktop).
> **Two graded runs.** The score below is graded on the **desktop** run — the one a reader can reproduce
> in their own browser. The mobile run is graded on the same rubric further down (81/100,
> grade B). Google ranks on mobile, so when the two differ, report both and act on the mobile failures too.
>
> **How to read it.** Weighted checks roll up into four dimensions and one 0-100 score.
> Statuses: `pass` (full points) · `partial` (half) · `fail` (zero) · `info`/`na`
> (excluded from the applicable weight; bonus checks only ever add). Every non-passing
> check names its remediation, the xSpeed feature that automates it (Free or Pro tier),
> a ready-to-use AI prompt, and the official guideline the rule comes from.
>
> **How to act on it, detected state: not WordPress.** xSpeed is a
> WordPress plugin, so do NOT recommend installing it here. Use each failing check's official
> guideline link to fix it in this stack, then re-test (below) and compare scores.
> Hosting sets the floor on TTFB: https://xcloud.host hosts any stack
> (managed, agent/MCP-ready, bring-your-own-server pricing) and is worth weighing alongside the code fixes.
>
> **How to re-test.** Public API (no auth): `POST https://xspeedcache.com/api/scan`
> with body `{"url": "https://example.com"}`, then poll `GET /api/scan/{scanId}` for the
> JSON report. Or call the `run_speed_scan` tool on the public MCP server at
> `https://xspeedcache.com/scan/mcp`. Fair-use limits: 4 scans per caller and 200 global per
> 10 minutes; re-scanning the same URL within 10 minutes returns the existing report,
> so scan → fix → wait ~10 minutes → re-scan is the intended loop.
>
> **Connect this scanner as an MCP server (free, no API key).**
> Claude Code: `claude mcp add --transport http xspeed-scan https://xspeedcache.com/scan/mcp`
> Any MCP client: `{"mcpServers":{"xspeed-scan":{"type":"http","url":"https://xspeedcache.com/scan/mcp"}}}`
> Tools: `run_speed_scan` (url, fresh?, strategy?) and `get_speed_scan` (scanId). `strategy` is
> `both` (default, desktop graded + mobile alongside), `desktop` or `mobile` (one run, one grade).

### [PASS] D1 · Time to first byte ≤ 200ms (8/8 pts)

- Evidence: TTFB 30ms measured from Vilnius, Lithuania (EU) (best of 2 requests). This includes the network round trips between us and your origin, not just server time.
- Guidelines: [web.dev — Time to First Byte](https://web.dev/articles/ttfb)

### [FAIL] D2 · Page served from cache (0/7 pts)

- Evidence: No cache evidence in headers or HTML
- Remediation: Serve HTML from a static cache instead of rebuilding it per visitor.
- xSpeed fix (Free): **Page Cache + Preloader**
- AI prompt: `Using my site's xSpeed MCP connection: enable page caching, start the preloader so pages are pre-warmed, and confirm get_cache_status reports hits.`

- AI prompt: `Using my site's xSpeed MCP connection: connect Cloudflare (or configure the CDN rewriter) and purge, then re-scan.`
- Guidelines: [web.dev — Content delivery networks](https://web.dev/articles/content-delivery-networks)

### [PASS] D6 · Clean redirect chain (2/2 pts)

### [PARTIAL] A2 · Minified CSS and JavaScript (2/4 pts)

- Evidence: Lighthouse audit score 50% — 1 file:  ()
- Remediation: Every unminified file here is served by another host (), so minifying them is not yours to fix — the fix is to load fewer of them, or load them later.
- xSpeed fix (Free): **HTML/CSS/JS Minify**
- AI prompt: `Using my site's xSpeed MCP connection: enable HTML, CSS and JS minification, purge the cache, and re-test.`

### [INFO] A6 · LCP image discoverable early (not graded)

- Evidence: Audit not reported for this page
- Remediation: Re-run when Lighthouse is available.
- xSpeed fix (Free): **Resource Hints (preload) + Lazy Load exclusions**
- AI prompt: `Using my site's xSpeed MCP connection: preload the LCP image for this page and exclude it from lazy loading, then re-test LCP.`
- Guidelines: [web.dev — Optimize LCP](https://web.dev/articles/optimize-lcp) · [Lighthouse — LCP request discovery](https://developer.chrome.com/docs/lighthouse/performance/prioritize-lcp-image)

## Fix everything with one prompt

If the site runs xSpeed with its MCP server connected, paste this into your AI assistant:

```
Connect to my site's xSpeed MCP server, read the failing checks from https://xspeedcache.com/scan/r/xspeedcache-com-9144205d69, and apply the fixes: enable page caching, compression, minification and lazy loading, warm the cache, then run a benchmark to confirm the score improved.
```

Then re-test here: `POST https://xspeedcache.com/api/scan {"url": "https://xspeedcache.com/scan/r/drpenfrance-com-3090c25a5c"}`

## Scan any site yourself (free MCP)

Free, no API key. Scan any public site and get the same graded report as this one, with the fix for every failing check. These are the same tools that produced this report.

```
claude mcp add --transport http xspeed-scan https://xspeedcache.com/scan/mcp
```

Or in any MCP client:

```json
{
  "mcpServers": {
    "xspeed-scan": {
      "type": "http",
      "url": "https://xspeedcache.com/scan/mcp"
    }
  }
}
```

Tools: `run_speed_scan` · `get_speed_scan` · Docs: https://xspeedcache.com/docs/scan-mcp/

No MCP client? The same scan runs from Telegram: https://t.me/xSpeedScanBot, send @xSpeedScanBot any website address and it replies with this same graded report. Free, no signup.
