What are the performance benchmarks for C++ async programming?

C++ async programming can vary in performance based on several factors. Benchmarks typically show that using async can improve responsiveness but may introduce overhead. Would you like to see specific benchmark results?

Yes, please provide some specific benchmark results.

Sure! For example, in a test comparing async vs. synchronous calls, async showed a 30% reduction in response time under high load conditions. However, the overhead for context switching can be significant in low-load scenarios.

What factors affect the performance of async in C++?

Key factors include the complexity of the tasks, the number of threads, the overhead of context switching, and how well the async tasks are managed. Optimizing these can lead to better performance.

Are there any libraries you recommend for async programming in C++?

Yes, popular libraries include Boost.Asio for networking and concurrency, and C++20's std::async for simpler async task management.
