A thread or process pool (also called pooling) indicates a management software that is being used to optimize and simplify the use of threads and/or processes within a program. Through pooling, you can submit the task (or tasks) in order to execute them to the pooler.

The pool is equipped with an internal queue of tasks pending and several threads or processes that execute them. A recurring concept in pooling is reusing: a thread (or process) is used several times for different tasks during its life cycle. This decreases the overhead of creating new threads or processes and increases the performance of the program.

Reuse is not a rule, but it is one of the main reasons that lead a coder to use pooling in their application.
