- Click Start speed test and keep other downloads closed.
- The test measures latency first, then download and upload throughput.
- Read Mbps and millisecond values together with the server label.
- Use Repeat to check consistency, and Stop to cancel an active test.

Wyjaśnienie techniczne
The page performs timed HTTP requests against a configured endpoint, using cache-busting and measured transferred bytes. Latency is estimated from small request round trips. Throughput is calculated from bytes transferred over elapsed time.
Browser speed tests are affected by HTTP overhead, server location, TCP ramp-up, device CPU, Wi-Fi, and the endpoint capacity. A result is not a substitute for an ISP diagnostic or a calibrated line-rate measurement. This project ships without a default speed endpoint; you must configure one you control.
Rozwiązywanie problemów
Test says no endpoint configured
Set speedtest.download_url, upload_url, and ping_url in app/config.local.php. The bundled test never uses a third-party server without configuration.
Results are much lower than expected
Close other transfers, use a wired connection where possible, and confirm the endpoint has enough bandwidth.
Upload fails
The endpoint must accept the upload method and size used by the test, and must allow cross-origin requests when hosted elsewhere.
Latency is unstable
Wi-Fi interference, bufferbloat, and background traffic affect jitter. Repeat at a quiet time.
