How can I optimize multithreading in C++?

How can I optimize multithreading in C++?

To optimize multithreading in C++, consider using thread pools, minimizing lock contention, and leveraging modern C++ features like std::async.

What are thread pools and how do they help?

Thread pools manage a collection of threads for executing tasks, reducing the overhead of thread creation and destruction.

Can you explain lock contention and how to minimize it?

Lock contention occurs when multiple threads compete for the same lock. You can minimize it by using finer-grained locks or lock-free data structures.

What modern C++ features should I use for multithreading?

Use features like std::thread, std::mutex, std::condition_variable, and std::async for better multithreading support.
