3. **Realistic Workload Scenarios** - Dealer analysis workflow simulation
4. **Resource Efficiency Tests** - Memory and CPU monitoring under load

### 🔧 Production-Ready Testing Infrastructure
- **Real API Integration**: Tests against production Letta Cloud API
- **Production Agent**: Uses actual AXLE agent (agent-01c2ef52-be32-401d-8d8f-edc561b39cbe)
- **Statistical Rigor**: Multiple iterations with mean, median, std dev analysis
- **Error Tracking**: Comprehensive exception handling and success rate monitoring
- **Memory Profiling**: Real-time resource usage tracking with psutil

### 🚀 Automated Validation Pipeline
- **One-command execution**: `python scripts/run_performance_validation.py --quick`
- **Automated reporting**: Generates markdown reports with validation status
- **CI/CD Ready**: Environment-based test configuration
- **Multiple execution modes**: Quick, full, and comparative-only testing

```

### Validation Methodology
1. **Multi-iteration testing** (5-10 runs per test) for statistical significance
2. **Real-time comparison** of Direct SDK vs MCP Server operations
3. **Resource monitoring** during test execution
4. **Success rate validation** with error tracking
5. **Performance improvement calculation** with threshold validation

### Key Metrics Tracked
- **Response Time**: Average, median, min, max, standard deviation
