How do async and multithreading compare in performance?

How do async and multithreading compare in performance?

Async programming allows tasks to run concurrently without blocking, while multithreading uses multiple threads to execute tasks in parallel. Generally, async can be more efficient for I/O-bound tasks, while multithreading is better for CPU-bound tasks.

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

Sure! If you're building a web server that handles many requests, async is ideal because it can manage multiple connections without creating a new thread for each one, saving resources.

What are the downsides of using async?

One downside of async is that it can lead to more complex code, especially with error handling and debugging. It also requires a good understanding of event loops.

Is multithreading easier to implement than async?

Multithreading can be easier to understand for those familiar with traditional programming models, but it introduces challenges like race conditions and deadlocks that can complicate implementation.
