What this tool can and cannot do
Timings are measured from our hosting server's location, not from your device, and cover the main HTML document only (not images, scripts or rendering). For full page-rendering metrics (Core Web Vitals) the tool can optionally include Google PageSpeed Insights results when an API key is configured.
Data sources: Server-side request from our host · Google PageSpeed Insights API (optional)
Understanding the results
TTFB (time to first byte) under 200 ms is excellent, under 600 ms acceptable. High TTFB usually means slow server-side code, no caching, or an overloaded host.
Troubleshooting
- Enable page caching, use a CDN, and keep your PHP/CMS versions up to date to reduce TTFB.
Frequently asked questions
Why is the result different from my own experience?
Distance matters. A server far from our test location will show higher connection times than for visitors nearby.
