WebRtcPerf FAQs

Question 1

What is WebRtcPerf and what does it do?

Accepted Answer

WebRtcPerf is an open-source tool designed for evaluating WebRTC service performance and quality. It simulates multiple concurrent WebRTC client connections to measure key real-time communication statistics.

Question 2

What performance metrics can WebRtcPerf measure?

Accepted Answer

It measures and aggregates critical RTC performance statistics such as CPU and memory usage, bitrate, Round Trip Time (RTT), packet loss, jitter, resolution, and frames per second (FPS), providing comprehensive insights into your service.

Question 3

Can WebRtcPerf simulate different network conditions for testing?

Accepted Answer

Yes, WebRtcPerf leverages the Traffic Controller (TC) framework on Linux to apply and dynamically change network constraints, allowing for realistic testing under various bandwidth, latency, and packet loss conditions.

Question 4

How does WebRtcPerf integrate with other monitoring and visualization tools?

Accepted Answer

WebRtcPerf offers seamless integration with Prometheus and Grafana via Pushgateway. This allows for external collection, visualization, and in-depth analysis of the performance metrics generated during your tests.

Question 5

How does WebRtcPerf simulate multiple client connections?

Accepted Answer

The tool uses NodeJS to spawn multiple headless Chromium browser sessions via Puppeteer. Each browser instance acts as an independent WebRTC client, facilitating large-scale concurrent session simulations.
