### Best Practices Demonstrated

- ✅ Standard library preference for compatibility
- ✅ Robust error handling with detailed feedback
- ✅ Comprehensive documentation with examples
- ✅ Modular, reusable code architecture
- ✅ Cross-platform compatibility maintained
- ✅ **NEW**: Performance testing methodologies
- ✅ **NEW**: Data export and persistence patterns
- ✅ **NEW**: System configuration analysis

## 🔧 Advanced Usage Examples

### Custom Performance Monitoring

```python
from netdiag import ping_latency_test, bandwidth_test
from netdiag.export import NetdiagLogger
import time

# Setup monitoring
logger = NetdiagLogger('network_monitor')
hosts = ['google.com', 'github.com', 'stackoverflow.com']

for host in hosts:
    # Comprehensive testing
    latency = ping_latency_test(host, count=10)
    bandwidth = bandwidth_test(host=host, duration=5)
    
    # Log results
    logger.log_test_result('monitoring', {
        'host': host,
        'latency': latency,
        'bandwidth': bandwidth,
        'timestamp': time.time()
    })
```

### Network Interface Analysis

```python
from netdiag import get_network_interfaces, get_default_gateway, analyze_network_config

# Get detailed interface information
interfaces = get_network_interfaces()
gateway = get_default_gateway()
config = analyze_network_config()

# Analyze configuration
if all([interfaces['success'], gateway['success'], config['success']]):
    print("🔧 Network Configuration Summary:")
    print(f"   Active Interfaces: {len(config['active_interfaces'])}")
    print(f"   Default Gateway: {gateway['gateway']}")
    print(f"   Primary Interface: {config.get('primary_interface', 'Unknown')}")
```

## 🆕 What's New in v1.1.0

### Major Enhancements
- 🚀 **Bandwidth Testing**: Real-world speed testing capabilities
- 🔧 **System Analysis**: Network interface and configuration discovery  
- 📊 **Export Functions**: Multi-format result export with logging
- ⚡ **Performance Tools**: Latency analysis and connection quality assessment
- 🎯 **Enhanced CLI**: 4 new command-line tools for advanced diagnostics

### Compatibility
- ✅ **Modern Python**: Upgraded to Python 3.7+ with modern type hints and features
- ✅ **Enhanced Architecture**: Clean code principles with dataclasses and protocols
- ✅ **Cross-Platform**: Windows, macOS, and Linux support preserved
- ✅ **Dependencies**: Still uses only Python standard library

## ⚠️ Limitations dan Considerations

### Performance Considerations
- **Bandwidth Testing**: May consume network data during testing
- **Port Scanning**: Large ranges may take significant time
- **Concurrent Operations**: Threading used but limited by network latency

### Platform-Specific Notes
- **Windows**: Some network interface data requires elevated privileges
- **macOS/Linux**: Better support for detailed interface information
- **Network Dependencies**: Internet connection required for external tests

### Rate Limiting
- **External APIs**: IP geolocation services may have rate limits
- **Bandwidth Tests**: Avoid excessive testing to prevent ISP throttling
- **DNS Queries**: Bulk operations should be used responsibly
