How do threading and asynchronous programming compare in performance?

Threading allows multiple threads to run concurrently, which can improve performance for CPU-bound tasks. Asynchronous programming, on the other hand, is more efficient for I/O-bound tasks as it allows other operations to run while waiting for I/O operations to complete.

Can you give examples of when to use each?

Sure! Use threading for tasks like image processing or calculations that require heavy CPU usage. Use asynchronous programming for tasks like web requests or file reading, where waiting for I/O is common.

What are the downsides of each approach?

Threading can lead to complexity with shared resources and potential deadlocks. Asynchronous programming can be harder to understand and debug due to its non-linear flow.

Which one is generally faster?

It depends on the task. For CPU-bound tasks, threading might be faster, while for I/O-bound tasks, asynchronous programming usually performs better.
