Recommendations

✅ CONCURRENCY: Parallel downloads (2 concurrent) are 50.2% faster than sequential. Consider increasing default concurrency.

✅ CONCURRENCY: 4 concurrent downloads are 50.2% faster than 2. Recommend maxConcurrent >= 4.

ℹ️ CONCURRENCY: 8 concurrent downloads show diminishing returns (0.0% improvement). Recommend maxConcurrent = 4 for balanced performance.

ℹ️ CPU: CPU usage is low (0.6%). System can handle higher concurrency.
