# Performance Considerations

## Performance Goals
- **Page Load:** Initial page render < 2 seconds, full functionality < 3 seconds
- **Interaction Response:** UI feedback within 100ms, complete operations < 500ms (excluding AI processing)
- **AI Operations:** Processing acknowledgment < 200ms, results delivery 1-3 seconds based on complexity
- **Animation FPS:** Maintain 60fps for all animations, 30fps minimum on low-end devices
- **Memory Usage:** < 100MB baseline, < 200MB with large task lists loaded

## Design Strategies

### AI-Specific Performance Optimizations
- **Request Batching:** Group multiple AI operations to reduce API calls
- **Progressive Loading:** Load essential UI first, AI features second
- **Smart Caching:** Cache AI-generated task templates and common responses
- **Response Time Optimization:** Show immediate acknowledgment of AI requests

### Data Management Performance
- **Virtual Scrolling:** Render only visible tasks in large lists (10,000+ tasks)
- **State Management:** Normalize task data to prevent duplication
- **Network Optimization:** GraphQL queries to fetch only needed data

### Mobile-Specific Optimizations
- **Battery Efficiency:** Reduce background processing when battery < 20%
- **Network Awareness:** Adapt functionality based on connection speed
- **Memory Management:** Aggressive cleanup of unused components

## Performance Budget
- **JavaScript Bundle:** < 500KB initial, < 1MB total with lazy loading
- **Critical CSS:** < 50KB inline, rest lazy loaded
- **Images:** WebP format, responsive sizing, lazy loading
- **API Response:** < 100KB per request, pagination for large datasets
