Jitter Test
Jitter is the variation between latency samples. High jitter can make a connection feel unstable even when average latency looks acceptable.
Run the packet loss testWhat jitter means
A stable connection returns packets with similar timing. When timing swings up and down, games feel inconsistent and calls can sound choppy.
How this site measures jitter
The packet loss test calculates jitter as the average absolute difference between neighboring round-trip latency samples.
