Performance Optimization Guide

Core Components

Performance Monitor

Monitors application performance metrics:

• Memory usage
• Response times
• Battery usage
• Network performance

Atomic Clock Service

Provides synchronized timestamps for performance tracking.

Performance Monitoring

Copy/// Performance Monitor Service
/// 
/// Monitors application performance metrics
class PerformanceMonitor {
  /// Collect performance metrics
  Future<void> collectMetrics() async {
    final metrics = PerformanceMetrics(
      memoryUsage: await _getMemoryUsage(),
      responseTime: await _getAverageResponseTime(),
      batteryLevel: await _getBatteryLevel(),
      networkLatency: await _getNetworkLatency(),
    );
    
    // Store metrics
    await _storeMetrics(metrics);
    
    // Check thresholds
    _checkThresholds(metrics);
  }
  
  /// Get memory usage
  Future<int> _getMemoryUsage() async {
    // Get current memory usage in MB
    return await _nativeMemoryService.getMemoryUsage();
  }
}

Memory Optimization

Copy/// Optimize memory usage
Future<void> optimizeMemory() async {
  // Clear caches if memory high
  final memoryUsage = await _getMemoryUsage();
  if (memoryUsage > _memoryWarningThreshold) {
    await _clearCaches();
    await _garbageCollect();
  }
}

Response Time Optimization

Copy/// Optimize response times
Future<void> optimizeResponseTime() async {
  // Use async operations
  // Cache frequently accessed data
  // Batch operations when possible
  // Use background processing for heavy operations
}

Battery Optimization

Copy/// Optimize battery usage
Future<void> optimizeBattery() async {
  // Reduce background activity when battery low
  final batteryLevel = await _getBatteryLevel();
  
  if (batteryLevel < 20) {
    // Reduce BLE scanning frequency
    await _reduceBLEScanning();
    // Reduce background sync frequency
    await _reduceBackgroundSync();
  }
}
