Test settings optional
Data allowance

These are payload ceilings. Probes and protocol overhead add data use. Transfers compete with other traffic. Measurement stops within 30 seconds; sharing can take longer.

Connection details automatically detected where possible
Network hintAvailable when you explore public observationsThe network shown may be your VPN or proxy.

Device context is detected where available. Unknown facts stay unknown.

Add what you know. Wi-Fi connects your device to a router; that router can use fibre, cable, LTE or 5G.

Changes apply to your next test.

Latency first. Speed included. How we measure ↗

01 / Latency

How long you wait.

Time for an HTTP reply, in milliseconds. Lower is better. We compare before transfers, during downloads and during uploads.

02 / Speed

How much you move.

Download and upload throughput, in Mbps. Higher moves files faster. A fast connection can still have slow replies when it gets busy.

03 / Meaning

Numbers, explained.

See whether replies slowed under load, what could affect everyday use, and how much evidence the test collected.
