Flask-SocketIO Timeout Errors when Handling Concurrent Connections
I'm sure I'm missing something obvious here, but I'm having a hard time understanding I'm experiencing timeout errors when trying to handle multiple concurrent connections using Flask-SocketIO, particularly when clients send rapid messages... I'm running Flask-SocketIO version 5.0.1 along with eventlet as the WSGI server. The scenario occurs when I have around 50 clients connected and they start sending messages in quick succession. I see timeout errors in the logs like `TimeoutError: The operation timed out`. Here’s a snippet of how I’ve set up my Flask-SocketIO server: ```python from flask import Flask from flask_socketio import SocketIO, emit app = Flask(__name__) socketio = SocketIO(app, cors_allowed_origins='*') @socketio.on('message') def handle_message(data): print('Received message: ' + data) emit('response', {'status': 'Message received'}, broadcast=True) if __name__ == '__main__': socketio.run(app, host='0.0.0.0', port=5000) ``` I’ve tried increasing the default timeout settings but that hasn’t resolved the scenario. Here’s how I've adjusted the timeout: ```python socketio = SocketIO(app, cors_allowed_origins='*', timeout=30) ``` Still, I encounter the same timeout errors under load. I've also considered using `async_mode='eventlet'`, but I'm not sure how to implement that correctly in my existing code. Any ideas on how to handle this situation better? Are there specific configurations or code patterns that could help improve performance under simultaneous connections? My development environment is macOS. Any help would be greatly appreciated! What's the correct way to implement this?
