What are the benefits of using a thread pool?

Using a thread pool can improve performance by reusing threads, reducing the overhead of thread creation and destruction.

Can you explain how it reduces overhead?

Sure! Creating and destroying threads can be resource-intensive. A thread pool maintains a set of active threads, allowing tasks to be executed without the need to create new threads each time.

Are there any downsides to using a thread pool?

Yes, one downside is that if the pool is too small, tasks may have to wait for a thread to become available, leading to delays.

How do I decide the size of a thread pool?

The size of a thread pool should be based on the number of available CPU cores and the nature of the tasks. A common approach is to set it to the number of cores plus some additional threads for I/O-bound tasks.
