**Intent:** It is often the case that tasks to be executed are short-lived and
|
||
|
|
the number of tasks is large. Creating a new thread for each task would make
|
||
|
|
the system spend more time creating and destroying the threads than executing
|
||
|
|
the actual tasks. Thread Pool solves this problem by reusing existing threads
|
||
|
|
and eliminating the latency of creating new threads.
|

**Applicability:** Use the Thread Pool pattern when
|
||
|
|
|
||
|
|
* you have a large number of short-lived tasks to be executed in parallel
