What is Network Speed Test?
Network Speed Test measures your connection by timing real requests against this site itself: eight favicon fetches for latency and jitter, repeated 540 KB downloads for throughput, and an optional 256 KB POST upload probe. A plain-language verdict tells you what the numbers mean - with no third-party API involved.
Key Benefits
- No ads, no third-party scripts, no tracking around your results
- Latency and jitter, not just headline bandwidth
- Measures the actual route to this site, not a synthetic server
- Upload probe falls back gracefully on static hosting
- Runs in seconds, entirely in your browser
Common Use Cases
- •Checking Wi-Fi quality before an important video call
- •Diagnosing why one specific site feels slow on your line
- •Comparing connections on mobile data versus home broadband
- •Verifying an ISP or router change actually improved latency
How to Test Your Connection Speed
- Start the test: Click the start button and keep the tab in the foreground - the probes take a few seconds.
- Read the four metrics: Download and upload show throughput, latency shows response delay, and jitter shows its stability.
- Use the verdict: The quality verdict tells you what the measured speed supports, from browsing to heavy streaming.
Key Features
- Latency from eight small same-domain requests with jitter stddev
- Download throughput from repeated 540 KB static asset fetches
- Optional upload probe via a 256 KB POST with graceful fallback
- Connection-quality verdict: excellent, good, fair, or slow
- Zero third-party APIs, zero ads, zero tracking pixels
- Runs entirely in your browser against this site alone
