**RPS** stands for Requests Per Second, a performance measurement that indicates how many requests a server can handle in one second. This metric is crucial in evaluating the capacity and scalability of web hosting solutions and applications. A high RPS value often signifies that a server can efficiently manage a substantial number of concurrent users or tasks, making it a critical consideration for organizations seeking to ensure reliability under peak traffic conditions. Optimizing RPS helps maintain user satisfaction by minimizing downtime and delays.
