3-Hour Debugging: How `time.sleep` in Async Functions Killed Our asyncio Concurrency

1. 1Identify potential bottlenecks in your async code using tools like asyncio's built-in debug mode
2. 2Replace time.sleep with asyncio.sleep to ensure non-blocking waits
3. 3Use async-friendly libraries and frameworks to avoid blocking calls
4. 4Test your async code with multiple concurrent tasks to ensure scalability
5. 5Analyze performance metrics to detect and fix concurrency issues

Backend developers and DevOps engineers can benefit from understanding the implications of using time.sleep in async functions to improve the performance and reliability of their asyncio-based applications

💡 Using time.sleep in async functions can block the event loop and kill concurrency, while asyncio.sleep allows for non-blocking waits
