How do async and threading compare in performance?

How do async and threading compare in performance?

Async programming allows for non-blocking operations, while threading involves multiple threads running concurrently. Async can be more efficient for I/O-bound tasks, while threading may be better for CPU-bound tasks.

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

Sure! If you're building a web server that handles many requests, async is ideal because it can manage multiple connections without blocking. In contrast, if you're performing heavy computations, threading might be more suitable.

What are the downsides of using async?

Async can introduce complexity in code, making it harder to read and debug. Additionally, not all libraries support async, which can limit its use.

Is there a performance benchmark comparing both?

Yes, benchmarks often show that async can handle more concurrent tasks with lower resource usage, but the exact performance can vary based on the specific use case.
