What is a common approach to improving the performance of a database application with a large number of concurrent users?

Connection pooling is a common approach to enhancing the performance of a database application with numerous concurrent users. It involves reusing and managing a pool of database connections rather than establishing a new connection for each user request. By minimizing the overhead of connection establishment and teardown, connection pooling reduces latency and improves overall application responsiveness, particularly in scenarios with high concurrency.
