How do different concurrency models compare in C++?

In C++, concurrency models like threads, async, and coroutines each have unique advantages. Would you like a detailed comparison?

Yes, please explain the differences between threads and async.

Threads provide parallel execution but require careful management of shared resources. Async, on the other hand, allows for non-blocking operations, making it easier to handle I/O without blocking the main thread.

What about coroutines? How do they fit into this?

Coroutines are a more modern approach, allowing you to write asynchronous code that looks synchronous. They can simplify complex control flows and improve readability.

Which model would you recommend for a high-performance application?

For high-performance applications, using threads for CPU-bound tasks and coroutines for I/O-bound tasks often yields the best results.
