How does asyncio compare to gevent for performance?

Both asyncio and gevent are popular for handling asynchronous tasks in Python, but they have different performance characteristics. Asyncio is built into Python and uses an event loop, while gevent uses greenlets for lightweight concurrency. Generally, gevent can be faster for I/O-bound tasks due to its cooperative multitasking, but asyncio can be more efficient for CPU-bound tasks.

Can you give me an example of when to use each?

Sure! Use asyncio when you're working with a lot of I/O-bound operations, like web scraping or handling multiple network requests. On the other hand, gevent is great for applications that require high concurrency with many simultaneous connections, like a chat server.

What are the downsides of using gevent?

One downside of gevent is that it can be less compatible with libraries that are not designed for cooperative multitasking. Additionally, debugging can be more complex due to the use of greenlets.

Is there a way to combine both libraries?

Yes, you can combine them by using gevent's monkey patching to make standard library functions cooperative. However, this can lead to unexpected behavior, so it's important to test thoroughly.
