Technical Architecture

Regression Detection Algorithm

// Calculate regression percentage
const regressionPercent = ((current.mean - baseline.mean) / baseline.mean) * 100;

// Apply thresholds
if (regressionPercent > 10) {
  return { status: 'fail', detected: true };
} else if (regressionPercent > 5) {
  return { status: 'warning', detected: true };
} else if (regressionPercent <= -5) {
  return { status: 'pass', message: 'Performance improved' };
}

Statistical Outlier Removal

Uses Tukey's fences method:

const q1 = percentile(sorted, 25);
const q3 = percentile(sorted, 75);
const iqr = q3 - q1;
const lowerFence = q1 - 1.5 * iqr;
const upperFence = q3 + 1.5 * iqr;

return samples.filter(s => s >= lowerFence && s <= upperFence);

Key Features

1. Automated PR Feedback

Every PR receives an automated comment with:

• Detailed JSON results
• Threshold reference
• Link to workflow run

2. Historical Baseline Management

• Version-based baseline storage

• Retention of last 10 baselines
• Clean baseline rotation
• Git-based version tracking

3. Developer-Friendly Local Execution

# Quick validation before PR
npm run benchmark:local -- --baseline=v2.3.5

# Deep analysis with multiple runs
