What do download, upload, latency, and jitter mean?
Download and upload measure HTTP throughput between your browser and the test node. Latency is round-trip response time, while jitter is how that latency varies across measurements.

Frequently asked questions
Why do speed test results vary between runs?
Wi-Fi signal, device load, proxies, ISP routing, and test-node load can all affect results. Repeat the test on the same device and network when possible.
Does a speed test use data?
Yes. The test transfers download and upload data. The amount depends on the test and connection speed; the page explains how upload data is counted.
