Internet Speed Test
What your speed test result means
Download affects streaming and large files. Upload matters for calls and cloud backups. Ping measures delay; jitter shows how much that delay varies.
How the SpeedXG speed test works
SpeedXG first samples latency, then transfers bounded payloads to measure throughput. Results reflect this device and path at this moment.
How accurate is this speed test?
SpeedXG measures real transfers from your browser. Results describe this device and path at this moment. Wi-Fi, congestion and server distance all affect the number.
What is ping in a speed test?
Ping is round-trip delay in milliseconds. Lower is better for games and calls. Jitter is how much that delay changes between samples.
How do I get the most accurate speed test?
Use Ethernet when you can, pause other traffic, and run two tests. Compare the WiFi speed test next to the router with a wired run to isolate wireless loss.
Mbps vs MB/s — which does this test use?
SpeedXG reports megabits per second (Mbps), the same unit ISPs advertise. Divide by 8 for megabytes per second.
