Performance Regression Detector
Detect performance regressions early in the development cycle through automated testing.
Detection Methods
- Baseline Comparison: Compare against historical performance data
- Statistical Analysis: Detect statistically significant changes
- Threshold Violations: Check against performance budgets
- 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
- Define performance benchmarks
- Set up automated performance testing in CI/CD
- Implement regression detection logic
- Configure notification and reporting
- 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
