Speed Test
Free speed test: measure download speed, upload speed, latency and jitter directly in your browser.
How does the speed test work?
It downloads and uploads data blocks from this server and derives throughput from the transfer times, then uses repeated probes to measure latency and jitter.
Why is the result lower than my broadband plan?
Wi-Fi, VPNs and shared servers all reduce throughput. To measure your line rate, use a wired connection and pick a nearby server.
What is jitter?
The variation between consecutive latency samples. For voice calls and gaming, low jitter matters more than high bandwidth.
