What are the performance differences between async and thread programming?

What are the performance differences between async and thread programming?

Async programming allows for non-blocking operations, which can lead to better performance in I/O-bound tasks. Threads, on the other hand, can be more efficient for CPU-bound tasks but may introduce overhead due to context switching.

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

Sure! If you're building a web server that handles many simultaneous requests, async programming is ideal because it can manage multiple connections without blocking. Threads might be better for tasks that require heavy computation.

What are the downsides of using async programming?

Async programming can be more complex to implement and debug. It also requires a different mindset, as you need to think in terms of events and callbacks.

Are there any specific languages that favor async programming?

Yes, languages like JavaScript (with Promises and async/await), Python (with asyncio), and C# (with async/await) are designed to support async programming effectively.
