The Node driver already comes with a connection pool, whether you want to use it or not. In fact, all officially supported MongoDB drivers are created according to unified standards and behave similarly, so in fact, all drivers used use connection pools to manage connections.
Connection pools can reduce the time it takes for applications to create links. Using connection pools will not make any difference to upper-layer applications. Correctly configuring the connection pool can optimize performance during times of high concurrency
