What are some common mistakes when using thread pools?

Some common mistakes include not configuring the pool size correctly, failing to handle exceptions, and not shutting down the pool properly.

How do I determine the right size for a thread pool?

The right size often depends on the number of available CPU cores and the nature of the tasks. A good starting point is to use the number of cores and adjust based on performance.

What happens if I set the thread pool size too high?

Setting the size too high can lead to excessive context switching, increased memory usage, and can actually degrade performance.

Can you explain how to properly shut down a thread pool?

To shut down a thread pool, you should call the shutdown method to stop accepting new tasks and then await termination to ensure all tasks complete.
