QPS stands for Queries Per Second. It is a measure of how many queries or requests a system can handle in one second. QPS is commonly used to evaluate the performance and scalability of servers, databases, and network services, especially in high-traffic environments like websites, APIs, and cloud services.
For example, if a web server has a QPS of 100, it means that it can process up to 100 requests per second. This metric is crucial for understanding how well a system can handle load and for planning capacity during peak usage times.
In the context of cloud services, providers often offer tools and services to help monitor and manage QPS. For instance, Tencent Cloud provides various monitoring and auto-scaling services that can help maintain optimal performance based on real-time QPS data.
