What are the performance differences between threading and multiprocessing?

Threading and multiprocessing are both techniques to achieve concurrency, but they have different performance characteristics. Threading is generally more lightweight and suitable for I/O-bound tasks, while multiprocessing can handle CPU-bound tasks better by utilizing multiple cores.

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

Sure! Use threading for tasks like web scraping or network requests where waiting for I/O is common. Use multiprocessing for tasks like data processing or computations that require heavy CPU usage.

What are the overhead costs associated with each?

Threading has lower overhead since threads share the same memory space, but it can lead to issues like race conditions. Multiprocessing has higher overhead due to the need for inter-process communication and separate memory spaces, but it avoids these concurrency issues.

Which one is easier to implement?

Threading is often considered easier to implement due to its simpler model and shared memory. However, it requires careful management to avoid concurrency issues. Multiprocessing can be more complex to set up but is safer for CPU-bound tasks.
