Optimizing WebSocket performance

WebSocket connections provide a powerful mechanism for real-time communication between clients and servers. To ensure the optimal performance and scalability of WebSocket applications, it’s essential to implement effective optimization techniques and a way to measure them. In this recipe, we will see how to benchmark WebSocket endpoints to test the number of connections supported by the connection and suggest practical tips and techniques to optimize WebSocket performance in your FastAPI applications.

Getting ready

Besides knowledge of how to set up a WebSocket endpoint, we will use the Implementing chat functionality with WebSockets recipe to benchmark the traffic supported. You can also follow the recipe by applying the strategy to your application.

Whether you apply it to your application or the chat functionality, it can be useful to include some message logs to be printed during the endpoint execution.

For example, for the WebSocket...
