What are the performance differences between C++ threading libraries?

There are several popular threading libraries in C++, including std::thread, Boost.Thread, and Intel TBB. Each has its own performance characteristics depending on the use case.

Can you provide benchmarks for these libraries?

Sure! Benchmarks typically show that std::thread performs well for basic threading tasks, while Boost.Thread offers more features but can be slightly slower. Intel TBB excels in parallel algorithms.

What factors should I consider when choosing a threading library?

You should consider factors like ease of use, performance, compatibility with your project, and the specific threading features you need.

Are there any specific use cases where one library outperforms the others?

Yes, for example, Intel TBB is often preferred for data parallelism in large-scale applications, while std::thread is great for simpler, lightweight tasks.
