+# Frontend Performance Optimization Guide
+
+## Quick Performance Solutions
+
+### 1. For Immediate Speed Improvement (Recommended)
+
+**Build and run the production version:**
+```bash
+npm run performance
+```
+This builds the optimized production version and runs it on port 3001, which will be significantly faster than the development server.
+
+### 2. For Development Speed
+
+**Use the fast development mode:**
+```bash
+npm run dev:fast
+```
+This runs the development server with optimized settings on port 3001.
+
+## Port Configuration
+
+- **Backend API**: Port 3000 (default)
+- **Frontend Development**: Port 3000 (default) or 3001 (fast mode)
+- **Frontend Production**: Port 3001
+
+## Performance Strategies
+
+### Development vs Production Performance
+
+| Mode | Speed | Port | Features | Use Case |
+|------|-------|------|----------|----------|
+| `npm run dev` | Slow | 3000 | Hot reload, debugging | Development |
+| `npm run dev:fast` | Medium | 3001 | Hot reload, optimized | Development |
+| `npm run performance` | Fast | 3001 | Optimized, no hot reload | Testing/Production |
+
+### Why Development Mode is Slower
+
+Development mode includes:
+- Hot module replacement (HMR)
+- Source maps
+- Unminified code
+- Development warnings
+- Type checking
+- ESLint checking
+
+### Production Mode Benefits
+
+Production mode provides:
+- Minified and optimized code
+- Tree shaking
+- Code splitting
+- Optimized images
+- Faster rendering
+- Smaller bundle sizes
+
+## Performance Optimization Techniques
+
+### 1. Code Splitting
+
+The Next.js config now includes automatic code splitting:
+- Vendor chunks are separated
+- Dynamic imports for large components
+- Route-based splitting
+
+### 2. Bundle Optimization
+
+- **SWC Minification**: Faster than Terser
+- **Package Optimization**: Optimized imports for UI libraries
+- **Tree Shaking**: Removes unused code
+
+### 3. Image Optimization
+
+- **WebP/AVIF formats**: Smaller file sizes
+- **Responsive images**: Automatic sizing
+- **Lazy loading**: Images load when needed
+
+### 4. Caching Strategies
+
+- **Static generation**: Pre-built pages
+- **Incremental Static Regeneration**: Fresh content with caching
+- **CDN optimization**: Distributed content delivery
+
+## Performance Monitoring
+
+### Analyze Bundle Size
+
+```bash
+npm run build:analyze
+```
+
+This will show you:
+- Bundle size breakdown
+- Largest dependencies
+- Optimization opportunities
+
+### Type Checking
+
+```bash
+npm run type-check
+```
+
+Ensures TypeScript types are correct without running the full dev server.
+
+## Advanced Optimizations
+
+### 1. Component-Level Optimizations
+
+```tsx
+// Use React.memo for expensive components
+const ExpensiveComponent = React.memo(({ data }) => {
+ return
{/* expensive rendering */}
+});
+
+// Use useMemo for expensive calculations
+const expensiveValue = useMemo(() => {
+ return expensiveCalculation(data);
+}, [data]);
+
+// Use useCallback for event handlers
+const handleClick = useCallback(() => {
+ // handle click
+}, []);
+```
+
+### 2. Lazy Loading
+
+```tsx
+// Lazy load components
+const LazyComponent = dynamic(() => import('./LazyComponent'), {
+ loading: () => Loading...
+});
+```
+
+### 3. Virtual Scrolling
+
+For large lists, consider virtual scrolling libraries:
+- `react-window`
+- `react-virtualized`
+
+## Environment-Specific Optimizations
+
+### Development Environment
+
+1. **Use Turbopack**: Already enabled in your config
+2. **Disable unnecessary features**: Remove console logs in production
+3. **Optimize imports**: Use the `optimizePackageImports` config
+
+### Production Environment
+
+1. **Enable compression**: Gzip/Brotli compression
+2. **Use CDN**: Serve static assets from CDN
+3. **Enable caching**: Browser and server-side caching
+4. **Monitor performance**: Use tools like Lighthouse
+
+## Troubleshooting Slow Performance
+
+### Common Issues
+
+1. **Large bundle size**: Use bundle analyzer
+2. **Unnecessary re-renders**: Use React DevTools Profiler
+3. **Slow API calls**: Implement caching and loading states
+4. **Heavy third-party libraries**: Consider alternatives or lazy loading
+
+### Performance Checklist
+
+- [ ] Use production build for testing
+- [ ] Implement code splitting
+- [ ] Optimize images
+- [ ] Minimize bundle size
+- [ ] Use React.memo where appropriate
+- [ ] Implement proper caching
+- [ ] Monitor Core Web Vitals
+
+## Recommended Workflow
+
+1. **Development**: Use `npm run dev:fast` for faster development
+2. **Testing**: Use `npm run performance` to test production-like performance
+3. **Production**: Use `npm run build && npm run start` for deployment
+
+## Performance Metrics to Monitor
+
+- **First Contentful Paint (FCP)**: < 1.8s
+- **Largest Contentful Paint (LCP)**: < 2.5s
+- **First Input Delay (FID)**: < 100ms
+- **Cumulative Layout Shift (CLS)**: < 0.1
+
+## Tools for Performance Analysis
+
+- **Lighthouse**: Built into Chrome DevTools
+- **WebPageTest**: Detailed performance analysis
+- **React DevTools Profiler**: Component-level performance
+- **Bundle Analyzer**: Bundle size analysis
