Load Testing Real-Time Systems
Learn how to simulate thousands of concurrent connections to find the breaking points of WebRTC and live data systems before real users do.
Why Real-Time Is Hard to Test
A REST endpoint can be load tested with simple request bursts. Real-time systems hold thousands of long-lived connections, each pushing and pulling continuously.
Load testing must model that sustained, stateful traffic, not just request counts.
What to Measure
- Concurrent connections the system holds.
- Messages per second in and out.
- End-to-end latency under load.
- Resource use: CPU, memory, file descriptors.
