Performance Regression Analysis
Performance Regression Analysis is the process of identifying and investigating decreases in application performance between software versions, builds, or configuration changes. It compares metrics such as response time, throughput, resource utilization, and latency to determine whether recent code, infrastructure, or dependency changes introduced regressions. The goal is to detect performance degradation early and isolate its root cause before release or production impact.
