1. Use the most up-to-date version of Node-RED: Upgrading to the most recent version of Node-RED can help improve performance as new versions are often optimized for better performance.
2. Use the latest version of Node.js: The latest version of Node.js contains performance improvements that can help Node-RED run faster.
3. Optimize your flows: Carefully examining your flows and minimizing the number of nodes can help improve performance.
4. Utilize caching: Caching can help reduce the amount of processing that needs to be done on each request.
5. Utilize queues: Queues can help reduce the number of concurrent requests that need to be processed at any given time.
6. Utilize clustering: Clustering can help distribute the load across multiple nodes which can help improve performance.
