In a high-load Spring Boot application, how does connection pooling optimize the performance?

Connection pooling optimizes performance by managing a pool of database connections, which reduces the overhead of creating and closing connections for each database request. This results in improved performance because it ensures efficient reuse of connections, minimizing the impact on the database server and reducing the overall resource consumption. High-load applications benefit significantly from connection pooling as it prevents exhausting database resources and mitigates latency.
