Page size shown is the uncompressed HTML document; when compression is on (see below), fewer bytes actually travel over the wire.
What does this test measure?
Enter a website and this tool loads it once from our server and measures the timings that your web host is responsible for: how long it takes to connect, the time to first byte (TTFB — how quickly the server starts responding), the total time to download the page, and the page’s (uncompressed) size. It also checks whether the site uses HTTPS and compression.
TTFB is the clearest signal of hosting quality. Under 200 ms is excellent; over a second usually means an overloaded shared server, a slow stack, or a host that’s simply too far from your visitors — all fixable by moving to a faster host.
Frequently Asked Questions
Is this the same as Google PageSpeed / Lighthouse?
No, and we’re honest about that. Lighthouse renders the full page in a browser and scores dozens of front-end factors. This tool measures the server-side timings your host controls — connection, TTFB, download time and page weight — which is exactly what you compare when choosing hosting.
What’s a good TTFB?
Under 200 ms is excellent, under 500 ms is good, up to a second is fair, and over a second is slow. A consistently slow TTFB is one of the strongest reasons to switch hosts.
Why is my result different each time?
Network conditions, caching and server load vary moment to moment. Run it a few times and look at the typical figure rather than a single reading.
Why did the test fail on my site?
The site may be down, serving only plain HTTP, using an invalid SSL certificate, or blocking automated requests. Check the domain and try again.
Do you store the URLs I test?
No. The test runs live and nothing you enter is saved — only a short-lived per-visitor counter to prevent abuse.
