This project provides benchmarking to compare the performance characteristics of WebSocket and WebRTC DataChannel communications in the context of online game development.
- Go with Pion WebRTC
- Go with FastWS
- JavaScript
go install .
go run .Access the application at: http://localhost:8080
The server is implemented in Go and functions as a loopback server (echoing received data back to the client). The client performs a series of transmissions, sending a specified number of messages containing random bytes of a predetermined size. It measures the total round-trip time.
Our performance analysis reveals that WebRTC demonstrates superior performance compared to WebSocket:
- Key Findings:
- WebRTC DataChannel achieves 1.15-2.5x faster communication speeds compared to WebSocket
- Performance advantages vary across different message sizes and browsers
- The performance gap is more pronounced with smaller message sizes and frequencies
- WebSocket performance improves relative to WebRTC as data volume increases
Note: These results represent averaged measurements from multiple test runs under controlled conditions. Actual performance may vary based on network conditions, message payload size, and specific implementation requirements.
