Latency and jitter test
Speed is not everything. Measure round-trip latency and jitter, the numbers that decide whether calls and video hold up.
Measure latency and jitter
Measures round-trip time from your browser to Purple's server over 20 samples. Jitter is the average change between consecutive round trips. Low and stable values matter most for calls, video, and gaming.
Latency, jitter, and why they matter
Latency is how long a round trip takes; jitter is how much that time varies between packets. A connection can post a high download figure and still drop video calls if jitter is high. Real-time traffic, voice, conferencing, and gaming, depends on low and stable latency far more than peak throughput.
Rough guide
- Under 30 ms latency with low jitter is excellent for real-time traffic.
- Jitter above 30 ms tends to cause audible glitches on calls.
- Spiky results often point to WiFi interference or an overloaded uplink.

Calls dropping on guest WiFi?
Jitter on a shared network is often a prioritisation problem. Purple works with your hardware's QoS and bandwidth controls so business-critical traffic stays smooth alongside guest use.
