How do C++20 coroutines improve performance in asynchronous programming?

C++20 coroutines allow for more efficient asynchronous programming by enabling lazy evaluation and reducing overhead.

Can you explain how lazy evaluation works in coroutines?

Lazy evaluation means that computations are deferred until their results are needed, which can save resources.

What are the main advantages of using coroutines over traditional threading?

Coroutines are lighter than threads, allowing for more concurrent operations without the heavy context switching.

Are there any performance benchmarks comparing coroutines and threads?

Yes, benchmarks often show that coroutines can handle more concurrent tasks with lower memory usage compared to threads.
