#performance-optimization

Systematically improve product performance and user experience. Performance metrics: 1. Core Web Vitals: Largest Contentful Paint (LCP <2.5s), First Input Delay (FID <100ms), Cumulative Layout Shift (CLS <0.1). 2. Time to First Byte (TTFB <600ms). 3. Time to Interactive (TTI <5s). 4. Application response times: API calls, database queries. Performance monitoring: 1. Real User Monitoring (RUM): actual user experience data. 2. Synthetic monitoring: automated performance tests. 3. Server monitoring: CPU, memory, disk usage. 4. CDN analytics: cache hit rates, edge performance. Optimization strategies: 1. Frontend: code splitting, lazy loading, image optimization, caching. 2. Backend: database query optimization, caching layers, microservices. 3. Infrastructure: CDN, load balancing, auto-scaling. Tools: Google PageSpeed Insights, New Relic, DataDog for monitoring. Performance budget: set thresholds, alert when exceeded, gate deployments on performance regression.

Deploy edge computing solutions with CDN optimization for improved performance and global content delivery. Edge architecture: 1. Edge locations: global distribution, 50+ locations worldwide, <50ms latency to users. 2. Edge functions: serverless compute at edge, request processing, content personalization. 3. Cache hierarchy: origin server → regional cache → edge cache, intelligent cache invalidation. CDN optimization: 1. Content delivery: static assets, dynamic content acceleration, image optimization. 2. Caching strategies: TTL configuration (1 hour for images, 5 minutes for APIs), cache tags for invalidation. 3. Compression: Brotli/Gzip compression (70% size reduction), WebP image format. Edge computing platforms: 1. AWS CloudFront + Lambda@Edge: global CDN, edge functions, real-time personalization. 2. Cloudflare Workers: serverless JavaScript execution, API processing, security filtering. 3. Azure CDN + Functions: content delivery, edge compute, IoT data processing. Performance optimization: 1. HTTP/3 support: QUIC protocol, reduced connection time, improved mobile performance. 2. Prefetching: predictive content loading, resource hints, service worker integration. 3. Adaptive delivery: device-specific content, network-aware optimization. Security at edge: 1. DDoS protection: traffic filtering, rate limiting, bot detection. 2. WAF integration: SQL injection prevention, XSS protection, custom rules. 3. SSL/TLS termination: certificate management, HTTP to HTTPS redirection. Monitoring: real-time analytics, edge performance metrics, user experience monitoring, geographic performance analysis.
