What are the performance implications of using stdatomic in C++?

What are the performance implications of using stdatomic in C++?

Using stdatomic can introduce overhead due to memory ordering and atomic operations, which may affect performance.

Can you explain how memory ordering affects performance?

Memory ordering defines how operations are seen by other threads. Stronger ordering can lead to more performance overhead.

Are there scenarios where stdatomic is preferred despite the overhead?

Yes, in multi-threaded applications where data consistency is critical, the benefits of stdatomic often outweigh the performance costs.

What alternatives exist if I want to avoid stdatomic?

You can use mutexes or other synchronization mechanisms, but they may also have their own performance trade-offs.
