--- description: Detect performance regressions in CI/CD --- # Performance Regression Detector Detect performance regressions early in the development cycle through automated testing. ## Detection Methods 1. **Baseline Comparison**: Compare against historical performance data 2. **Statistical Analysis**: Detect statistically significant changes 3. **Threshold Violations**: Check against performance budgets 4. **Trend Analysis**: Identify gradual degradation over time ## Metrics to Monitor - Response time percentiles (p50, p95, p99) - Throughput (requests per second) - Resource utilization (CPU, memory) - Bundle sizes and load times - Database query performance ## Process 1. Define performance benchmarks 2. Set up automated performance testing in CI/CD 3. Implement regression detection logic 4. Configure notification and reporting 5. Create remediation workflows ## Output Provide: - Performance test suite setup - Baseline performance data collection - CI/CD integration configuration - Regression detection thresholds - Automated reporting setup - Pull request comment integration - Remediation workflow documentation
