+
+## Key Findings
+
+### Optimal Configuration
+- **5 agents** achieved perfect success rate
+  - Average response time: 6.7s
+  - Peak CPU: 0.0%
+  - Peak Memory: 3911.8MB (0.0%)
+  - Memory per agent: 340.3MB
+  - Cost score: 20.49
+
+## Recommendations
+
+1. **Recommended max agents:** 5 for stable operation
+2. **Monitor closely:** 5+ agents
+3. **Implement circuit breaker** when failure rate exceeds threshold
