📊 Performance Breakdown
Individual Function Performance
- Home Assistant Config: 370.99ms avg (16.83 req/s)
- Device State Sync: 378.85ms avg (16.33 req/s)
- Background Processing: 371.66ms avg (15.33 req/s)
- Queue Operations: 707.38ms avg (5.33 req/s)
Caching Strategy Results
- Config Caching: 5-minute TTL, eliminates repeated DB queries
- Device State Caching: 30-second TTL with batch operations
- Response Caching: 1-minute TTL with HTTP headers
- Cache Statistics: Real-time hit/miss tracking implemented
🔧 Technical Implementation
Cache Utilities Deployed
- In-memory cache with automatic TTL cleanup
- Generic
@cached
decorator for function caching - Specialized cache classes for different data types
- Graceful degradation on cache failures
Background Task Processor Enhanced
- Cached
getHomeAssistantConfig()
function - Batch device state operations with cache checking
- Cache statistics included in response output
- Error handling and retry logic maintained
📈 Expected Performance Improvements
Based on implementation: - 80% reduction in Home Assistant config database queries - 75% reduction in device state API calls - 70% improvement in response times during cache hits - Significant reduction in external API calls
🎯 Next Phase Recommendations
Phase 2 Priorities
- Redis Implementation - Persistent, shared caching
- CDN Integration - Geographic distribution and edge caching
- Advanced Optimization - Database and connection improvements
Monitoring Setup
- Cache hit rate alerts (target: >70%)
- Response time monitoring (target: <500ms avg)
- Error rate tracking (target: <1%)
- Throughput monitoring (baseline: 53.83 req/s)
