Introduction
Run continuous ping frames against any WebSocket endpoint and visualize round-trip latency over time. The lab reports min, max, average, and p95 RTT so you can compare regions, VPNs, or gateway configs.
Step-by-step
- Enter a WebSocket URL that accepts text ping frames
- Connect, set interval, and Start sampling
- Review the sparkline and summary stats
- Export or stop the run when done
Worked example
Connect to your production gateway with a 1s ping interval for 60 seconds and confirm p95 RTT stays under your target.
Use cases
- Compare latency to multiple WebSocket regions
- Watch jitter during a long-running session
- Validate SLA targets before launch
Frequently asked questions
How is RTT measured?
Each sample records the time between sending a ping frame and the next inbound message. For echo servers this approximates true round-trip time.
