What are the performance benchmarks for different thread libraries?

Performance benchmarks for thread libraries can vary based on the specific use case. Are you looking for benchmarks on specific libraries like pthreads, OpenMP, or C++11 threads?

Yes, I'm particularly interested in pthreads and C++11 threads.

Pthreads generally offer lower-level control and can be more efficient for fine-tuned applications, while C++11 threads provide a higher-level abstraction that simplifies multithreading. Benchmarks show that pthreads can outperform C++11 threads in CPU-bound tasks, but C++11 threads are often easier to use.

What about scalability and ease of use?

C++11 threads are designed for ease of use with features like RAII and automatic resource management, making them more scalable for developers. Pthreads require more manual management, which can lead to complexity in larger applications.

Are there any specific benchmarks I should look at?

Yes, you can look at benchmarks from sources like the Computer Language Benchmarks Game or specific research papers that compare these libraries under various workloads.
