Test payload

The test downloads the selected amount of generated data. Mobile traffic charges may apply.

01

What it measures

Five request samples estimate connection latency. A streamed download then measures application-level throughput over your current route.

02

What it stores

Nothing in your browser. There are no analytics scripts, advertising tags, accounts, or persistent result identifiers.

03

How to interpret it

Results describe this route at this moment. Wi-Fi quality, congestion, distance, and your provider can all affect the reading.
