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

Using threads in C++ can improve performance by allowing concurrent execution, but it also introduces overhead and complexity.

What kind of overhead are we talking about?

The overhead includes context switching, synchronization costs, and potential cache contention, which can negate performance gains.

How can I minimize these overheads?

You can minimize overhead by optimizing thread management, using thread pools, and minimizing shared data access.

Are there specific scenarios where threading is not beneficial?

Yes, for tasks that are I/O bound or have low computational demand, the overhead of threading may outweigh its benefits.
