How can I troubleshoot performance issues with async middleware?

I'm experiencing performance issues with my async middleware in my Node.js application. What should I check?

First, check if your async functions are properly awaited. Unhandled promises can lead to performance bottlenecks.

I've ensured all promises are awaited. What else could be causing the slowdown?

Look into the middleware order. If a slow middleware is placed before others, it can affect overall performance.

That makes sense. Are there any tools I can use to monitor the performance of my middleware?

Yes, you can use tools like Node.js built-in profiler, or APM solutions like New Relic or Datadog to monitor performance.
