How does the performance of Python's asyncio library compare to traditional threading?

The asyncio library is designed for concurrent code execution using the async/await syntax, which can be more efficient than traditional threading for I/O-bound tasks. It avoids the overhead of thread management and context switching.

Can you give me an example of when to use asyncio over threading?

Sure! If you're building a web scraper that makes multiple HTTP requests, using asyncio can help you handle many requests concurrently without blocking, making it faster than using threads.

What are some limitations of using asyncio?

Some limitations include its complexity for beginners, the need for all libraries to support async, and it being less effective for CPU-bound tasks where traditional threading or multiprocessing might be better.

Are there any benchmarks comparing asyncio and threading?

Yes, there are several benchmarks available online. Generally, asyncio performs better for I/O-bound tasks, while threading may perform better for CPU-bound tasks. It really depends on the specific use case.
