How can I optimize performance using ForkJoin in Java?

To optimize performance with ForkJoin, ensure you are using the right threshold for splitting tasks and avoid excessive task creation.

What is the ideal threshold for splitting tasks?

The ideal threshold often depends on the task complexity, but a common starting point is around 1000 to 5000 elements.

Can you give an example of a task that benefits from ForkJoin?

Sure! A common example is parallelizing a large array processing, like summing elements or sorting.

Are there any pitfalls I should be aware of?

Yes, be cautious of over-splitting tasks, which can lead to overhead and reduce performance instead of improving it.
