What are the differences between thread pools and async in C++?

What are the differences between thread pools and async in C++?

Thread pools manage a collection of threads for executing tasks, while async allows for non-blocking operations.

Can you explain how thread pools improve performance?

Thread pools reduce the overhead of thread creation and destruction, allowing for better resource management and faster execution.

When should I use async instead of thread pools?

Use async for I/O-bound tasks where you want to avoid blocking, while thread pools are better for CPU-bound tasks.

Are there any downsides to using thread pools?

Yes, thread pools can lead to resource contention and may not be suitable for tasks that require high responsiveness.
