What are the performance benchmarks for C++11?

What are the performance benchmarks for C++11?

C++11 introduced several features that improved performance, such as move semantics and multithreading. Benchmarks show significant speedups in certain applications.

Can you explain move semantics and how it affects performance?

Move semantics allow resources to be transferred rather than copied, reducing overhead and improving performance, especially in container classes.

What about multithreading? How does C++11 handle it?

C++11 introduced the <thread> library, which simplifies multithreading by providing a standard way to create and manage threads, enhancing performance in concurrent applications.

Are there any specific benchmarks that highlight these improvements?

Yes, benchmarks like the C++ Benchmark Suite show C++11 outperforming C++03 in various scenarios, particularly in applications utilizing move semantics.
