Queries-per-second
(also QPS)
Queries-per-second definition
Queries-per-second is a metric for measuring how fast a computer system can handle incoming requests. It helps assess and improve the performance of websites, databases, and network devices. When a system’s QPS is too slow, it might need upgrades or optimizations to handle more requests. Monitoring and managing QPS is vital to keeping technical systems running smoothly.

Queries-per-second measure:
Benchmarking: QPS is a standard metric for stress tests and system comparisons.
SLA Adherence: Ensuring QPS meets Service Level Agreements’ criteria guarantees consistent service quality.
Issue Detection: Abnormal QPS patterns can indicate software, infrastructure, or security issues.
Load Balancing: QPS data helps distribute traffic effectively across servers or nodes.
Resource Allocation: QPS informs CPU, memory, or bandwidth distribution decisions.
User Behavior Analysis: QPS offers insights into peak usage times and patterns.
