What are the performance benchmarks for Rust's async features?

Rust's async features are designed for high performance. Benchmarks show that they can handle thousands of concurrent tasks efficiently.

How do these benchmarks compare to other languages like JavaScript or Python?

Rust's async performance often outperforms JavaScript and Python, especially in CPU-bound tasks, due to its zero-cost abstractions.

Can you provide specific numbers or examples from the benchmarks?

Sure! For instance, in a benchmark test, Rust's async I/O can handle over 100,000 concurrent connections, while Node.js handles around 30,000.

What factors influence the performance of async in Rust?

Key factors include the efficiency of the async runtime, the use of non-blocking I/O, and how well the code is optimized for concurrency.
