Recommendations
Ordered by expected impact.
1. Eliminate render-blocking resources
Impact: low. Estimated saving: 83 ms. Category: rendering.
1 stylesheet or script must download before the first paint. They held up rendering for up to 83 ms after the HTML arrived. The browser can't paint anything until render-blocking CSS and synchronous scripts in the <head> are downloaded and executed, so visitors stare at a blank screen.
How to fix:
- Add defer or async to scripts that are not needed for the first render.
- Inline critical CSS and load the rest asynchronously (media attribute or rel=preload).
- Remove unused stylesheets and combine small ones.

2. Serve static assets with an efficient cache policy
Impact: low. Estimated saving: 16 KB. Category: caching.
2 static resources have a cache lifetime under 7 days (16 KB that returning visitors download again). Long cache lifetimes let repeat visitors and subsequent page views skip the network entirely for assets that rarely change.
How to fix:
- Use fingerprinted file names (e.g. app.3f9a1c.js) and serve them with Cache-Control: public, max-age=31536000, immutable.
- Give images and fonts at least 30 days of cache lifetime.

Page structure
369 DOM elements, maximum depth 12. Visually complete at 2.9 s.
Test conditions
- Browser: Chrome/152.0.7977.64 on Cloudflare Browser Run, in San Jose, US
- Viewport: 1350×940 at 1× pixel density
- Network: Cable, 10 Mbps down, 10 Mbps up, 40 ms latency
- CPU: slowed 2.4× to match a reference benchmark index of 1000 (the test machine scored 2380)
- Browser Run sends traffic through an egress proxy, so connections use HTTP/1.1 and DNS lookups are not visible in the waterfall. Sites that rely on HTTP/2 multiplexing may measure slightly slower than in a regular browser.
Using this report
- Work through the recommendations in order. Impact and savings are estimates from this single lab run.
- Resources on other domains (third-party) usually can't be changed in the site's code: remove, defer or lazy-load them instead.
- Lab results vary between runs. After deploying a fix, test the same URL again at https://pagebench.dev/ and compare with this report.
- PageBench tests public URLs only; it can't reach localhost or private networks.
