A little less internet jargon.
A plain-language glossary of the numbers and settings used in your speed test.

Download
The rate at which your device receives data from the measurement destination. Shown in megabits per second (Mbps) by default. Higher throughput helps with large files and simultaneous streams.
Upload
The rate at which your device sends data. Upload capacity matters for sending files, cloud backups and outgoing video calls.
Ping / HTTP latency
The round-trip time for a small HTTP request, including browser and server overhead. This is not ICMP ping, and it is not latency to a specific game server.
Jitter
Weighted variation between idle latency samples, as computed by LibreSpeed. Larger spikes receive more weight.
Single and Multi
Single sends one measurement request at a time. Multi sends four in parallel and calculates aggregate throughput over their shared wall-clock interval. HTTP/2 or HTTP/3 may carry these requests over the same physical connection; the browser controls that behavior.
Mbps and MB/s
A megabit is one eighth of a megabyte. Divide Mbps by eight to express the same rate in MB/s. Changing the display unit does not change the underlying measurement.
Public IP and network provider
A public IP is the address visible to the website. A network provider label comes from the IP’s network registration and can describe a VPN, mobile gateway or corporate network rather than your billing provider.
Edge server
A network location chosen by routing. Automatic routing does not always mean the geographically closest location. Our server selector changes the measurement endpoint, not a guaranteed city.
