What are the performance differences between async and sync programming?

What are the performance differences between async and sync programming?

Async programming allows multiple tasks to run concurrently, improving performance in I/O-bound operations. Sync programming runs tasks sequentially, which can lead to blocking and slower performance.

Can you give me an example of when to use async over sync?

Sure! Use async when dealing with tasks like web requests or file I/O, where waiting for a response can be time-consuming. Sync is better for CPU-bound tasks that require immediate execution.

What are the downsides of using async programming?

Async programming can introduce complexity, making code harder to read and debug. It also requires a good understanding of callbacks, promises, or async/await patterns.

How does async programming affect resource management?

Async programming can lead to better resource utilization since it allows other tasks to run while waiting for I/O operations, reducing idle time.
