A standout amongst the most important features to enhance performance in Spring MVC is connection pooling. In this mechanism, N number of database connections are created and managed in a pool to increase the application's performance. When an application needs to utilize a connection, it just requests a connection, uses it, and then returns it to the pool. The main advantage of this procedure is that there are connections promptly available in the connection pool, so they can be utilized right away. The pool itself deals with the life cycle of the connection, so the developer doesn't have to wait for the connection to get established.
