Use when asked to \"speed up my site\", \"optimize performance\", \"reduce load time\", \"fix slow loading\", \"improve page speed\", or \"performance audit\".\nlicense: MIT\nmetadata:\n  author: web-quality-skills\n  version: \"2.0\"\n---\n\n# Performance optimization\n\nEvidence-led performance optimization using real-user signals for prioritization and browser traces for diagnosis. Focuses on loading speed, runtime responsiveness, and resource delivery.\n\n## How it works\n\n1. If a page can run, read [the measurement workflow](references/MEASUREMENT.md) and establish a field-plus-lab baseline before editing.\n2. Prioritize poor real-user Core Web Vitals. Use a DevTools performance trace and its focused insights to find the cause.\n3. Inspect and change only the code or assets connected to measured bottlenecks.\n4. Re-run equivalent lab measurements and report before/after values, conditions, and uncertainty. Field verification remains pending until enough new user data arrives.\n\nWhen no runnable page exists, perform static inspection but call findings **hypotheses**, not measured regressions. Include the command or browser workflow that can verify each high-impact hypothesis.\n\nPrefer a browser tool that records a performance trace and exposes focused insights. With Chrome DevTools MCP, use `performance_start_trace` and `performance_analyze_insight`; do not route performance through `lighthouse_audit`, which covers non-performance Lighthouse categories.\n\n## Starting performance budget\n\nBudgets must reflect the product's target devices, networks, page types, and user journeys. The values below are initial guardrails for a typical content or commerce page, not universal pass/fail criteria. Preserve an existing project budget when one is already defined.\n\n| Resource | Budget | Rationale |\n|----------|--------|-----------|\n| Total page weight | < 1.5 MB | Bounds transfer time and data cost on constrained target networks; calibrate with representative pages |\n| JavaScript (compressed) | < 300 KB | Protect parse and execution cost |\n| CSS (compressed) | < 100 KB | Limit render-blocking work |\n| Images (above-fold) | < 500 KB | Protect likely LCP resources |\n| Fonts | < 100 KB | Limit critical font transfer |\n| Third-party | < 200 KB | Bound code outside product control |\n\n## Critical rendering path\n\n### Server response\n* **TTFB < 800ms.** Time to First Byte should be fast. Use CDN, caching, and efficient backends.\n* **Enable compression.** Gzip or Brotli for text assets. Brotli preferred (15-20% smaller).\n* **HTTP/2 or HTTP/3.** Multiplexing reduces connection overhead.\n* **Edge caching.** Cache HTML at CDN edge when possible.\n* **Consider Early Hints (HTTP 103) for measured document latency.** If a trace shows slow HTML generation and stable critical subresources, send an interim `103` with `Link` headers before the normal final response from the same request. Use HTTP/2 or later. A CDN may synthesize the `103` from `Link` headers on an earlier `200`, or the origin/edge handler can emit it directly. Unsupported clients continue to the final response, but confirm current browser and infrastructure support. Limit hints to proven critical preloads or preconnects: inaccurate hints waste bandwidth. Cloudflare reported a 20–30% LCP improvement in an artificial, image-heavy test; treat that as a vendor case study, not an expected saving, and measure your result. See [MDN's 103 implementation example](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Status/103) and [the Cloudflare study](https://blog.cloudflare.com/early-hints-performance/).\n\n### Resource loading\n\n**Preconnect to required origins:**\n```html\n<link rel=\"preconnect\" href=\"https://fonts.googleapis.com\">\n<link rel=\"preconnect\" href=\"https://cdn.example.com\" crossorigin>\n```\n\n**Preload critical resources:**\n\nPreload only resources whose late discovery is visible in the trace. Each preload competes for bandwidth and an unnecessary high-priority request can delay LCP.\n\n```html\n<!-- LCP image -->\n<link rel=\"preload\" href=\"/hero.webp\" as=\"image\" fetchpriority=\"high\">\n\n<!-- Critical font -->\n<link rel=\"preload\" href=\"/font.woff2\" as=\"font\" type=\"font/woff2\" crossorigin>\n```\n\n**Prerender likely-next navigations** with the [Speculation Rules API](https://developer.chrome.com/docs/web-platform/prerender-pages):\n```html\n<script type=\"speculationrules\">\n{\n  \"prerender\": [{\n    \"where\": { \"href_matches\": \"/*\" },\n    \"eagerness\": \"moderate\"\n  }]\n}\n</script>\n```\n`moderate` waits for a stronger intent signal than eager modes. Measure prediction hit rate, transferred bytes, and server cost; a wrong prerender is roughly an unused navigation. See [core-web-vitals → LCP](../core-web-vitals/SKILL.md#lcp-largest-contentful-paint) for the tradeoffs and the `prerenderingchange` gating needed for analytics.\n\n**Defer non-critical CSS:**\n```html\n<!-- Critical CSS inlined -->\n<style>/* Above-fold styles */</style>\n\n<!-- Non-critical CSS -->\n<link rel=\"preload\" href=\"/styles.css\" as=\"style\" onload=\"this.onload=null;this.rel='stylesheet'\">\n<noscript><link rel=\"stylesheet\" href=\"/styles.css\"></noscript>\n```\n\n### JavaScript optimization\n\n**Defer non-essential scripts:**\n```html\n<!-- Parser-blocking (avoid) -->\n<script src=\"/critical.js\"></script>\n\n<!-- Deferred (preferred) -->\n<script defer src=\"/app.js\"></script>\n\n<!-- Async (for independent scripts) -->\n<script async src=\"/analytics.js\"></script>\n\n<!-- Module (deferred by default) -->\n<script type=\"module\" src=\"/app.mjs\"></script>\n```\n\n**Code splitting patterns:**\n```javascript\n// Route-based splitting\nconst Dashboard = lazy(() => import('./Dashboard'));\n\n// Component-based splitting\nconst HeavyChart = lazy(() => import('./HeavyChart'));\n\n// Feature-based splitting\nif (user.isPremium) {\n  const PremiumFeatures = await import('./PremiumFeatures');\n}\n```\n\n**Tree shaking best practices:**\n```javascript\n// ❌ Imports entire library\nimport _ from 'lodash';\n_.debounce(fn, 300);\n\n// ✅ Imports only what's needed\nimport debounce from 'lodash/debounce';\ndebounce(fn, 300);\n```\n\n## Image optimization\n\n### Format selection\n| Format | Use case | Browser support |\n|--------|----------|-----------------|\n| AVIF | Photos, best compression | 92%+ |\n| WebP | Photos, good fallback | 97%+ |\n| PNG | Graphics with transparency | Universal |\n| SVG | Icons, logos, illustrations | Universal |\n\n### Responsive images\n```html\n<picture>\n  <!-- AVIF for modern browsers -->\n  <source \n    type=\"image/avif\"\n    srcset=\"hero-400.avif 400w,\n            hero-800.avif 800w,\n            hero-1200.avif 1200w\"\n    sizes=\"(max-width: 600px) 100vw, 50vw\">\n  \n  <!-- WebP fallback -->\n  <source \n    type=\"image/webp\"\n    srcset=\"hero-400.webp 400w,\n            hero-800.webp 800w,\n            hero-1200.webp 1200w\"\n    sizes=\"(max-width: 600px) 100vw, 50vw\">\n  \n  <!-- JPEG fallback -->\n  <img \n    src=\"hero-800.jpg\"\n    srcset=\"hero-400.jpg 400w,\n            hero-800.jpg 800w,\n            hero-1200.jpg 1200w\"\n    sizes=\"(max-width: 600px) 100vw, 50vw\"\n    width=\"1200\" \n    height=\"600\"\n    alt=\"Hero image\"\n    loading=\"lazy\"\n    decoding=\"async\">\n</picture>\n```\n\n### LCP image priority\n```html\n<!-- Above-fold LCP image: eager loading, high priority -->\n<img \n  src=\"hero.webp\" \n  fetchpriority=\"high\"\n  loading=\"eager\"\n  decoding=\"sync\"\n  alt=\"Hero\">\n\n<!-- Below-fold images: lazy loading -->\n<img \n  src=\"product.webp\" \n  loading=\"lazy\"\n  decoding=\"async\"\n  alt=\"Product\">\n```\n\n## Font optimization\n\n### Loading strategy\n```css\n/* System font stack as fallback */\nbody {\n  font-family: 'Custom Font', -apple-system, BlinkMacSystemFont, \n               'Segoe UI', Roboto, sans-serif;\n}\n\n/* Prevent invisible text */\n@font-face {\n  font-family: 'Custom Font';\n  src: url('/fonts/custom.woff2') format('woff2');\n  font-display: swap; /* or optional for non-critical */\n  font-weight: 400;\n  font-style: normal;\n  unicode-range: U+0000-00FF; /* Subset to Latin */\n}\n```\n\n### Preloading critical fonts\n```html\n<link rel=\"preload\" href=\"/fonts/heading.woff2\" as=\"font\" type=\"font/woff2\" crossorigin>\n```\n\n### Variable fonts\n```css\n/* One file instead of multiple weights */\n@font-face {\n  font-family: 'Inter';\n  src: url('/fonts/Inter-Variable.woff2') format('woff2-variations');\n  font-weight: 100 900;\n  font-display: swap;\n}\n```\n\n## Caching strategy\n\n### Cache-Control headers\n```\n# HTML (short or no cache)\nCache-Control: no-cache, must-revalidate\n\n# Static assets with hash (immutable)\nCache-Control: public, max-age=31536000, immutable\n\n# Static assets without hash\nCache-Control: public, max-age=86400, stale-while-revalidate=604800\n\n# API responses\nCache-Control: private, max-age=0, must-revalidate\n```\n\n### Service worker caching\n```javascript\n// Cache-first for static assets\nself.addEventListener('fetch', (event) => {\n  if (event.request.destination === 'image' ||\n      event.request.destination === 'style' ||\n      event.request.destination === 'script') {\n    event.respondWith(\n      caches.match(event.request).then((cached) => {\n        return cached || fetch(event.request).then((response) => {\n          const clone = response.clone();\n          caches.open('static-v1').then((cache) => cache.put(event.request, clone));\n          return response;\n        });\n      })\n    );\n  }\n});\n```\n\n## Runtime performance\n\n### Avoid layout thrashing\n```javascript\n// ❌ Forces multiple reflows\nelements.forEach(el => {\n  const height = el.offsetHeight; // Read\n  el.style.height = height + 10 + 'px'; // Write\n});\n\n// ✅ Batch reads, then batch writes\nconst heights = elements.map(el => el.offsetHeight); // All reads\nelements.forEach((el, i) => {\n  el.style.height = heights[i] + 10 + 'px'; // All writes\n});\n```\n\n### Debounce expensive operations\n```javascript\nfunction debounce(fn, delay) {\n  let timeout;\n  return (...args) => {\n    clearTimeout(timeout);\n    timeout = setTimeout(() => fn(...args), delay);\n  };\n}\n\n// Debounce scroll/resize handlers\nwindow.addEventListener('scroll', debounce(handleScroll, 100));\n```\n\n### Use requestAnimationFrame\n```javascript\n// ❌ May cause jank\nsetInterval(animate, 16);\n\n// ✅ Synced with display refresh\nfunction animate() {\n  // Animation logic\n  requestAnimationFrame(animate);\n}\nrequestAnimationFrame(animate);\n```\n\n### Virtualize long lists\n```javascript\n// For lists > 100 items, render only visible items\n// Use libraries like react-window, vue-virtual-scroller, or native CSS:\n.virtual-list {\n  content-visibility: auto;\n  contain-intrinsic-size: 0 50px; /* Estimated item height */\n}\n```\n\n### Smooth navigations with View Transitions\n\nThe [View Transitions API](https://developer.chrome.com/docs/web-platform/view-transitions) lets the browser cross-fade (or custom-animate) between two DOM states using a single GPU-composited snapshot — no double-render, no layout thrash, and the snapshot doesn't count toward CLS.\n\n**Same-document (SPA-style) — Baseline 2026:**\n```javascript\n// Wrap the DOM mutation that swaps the view\nfunction navigate(newView) {\n  if (!document.startViewTransition) return swapDOM(newView);\n  document.startViewTransition(() => swapDOM(newView));\n}\n```\n\n**Cross-document (MPA-style) — Chromium-stable, progressive enhancement elsewhere:**\n```css\n/* On both source and destination pages */\n@view-transition { navigation: auto; }\n```\nThat's the entire integration — same-origin navigations now fade automatically. To opt specific elements into shared-element transitions (e.g. a thumbnail expanding into a hero), give them a matching `view-transition-name`:\n```css\n.product-thumb[data-id=\"42\"], .product-hero { view-transition-name: product-42; }\n```\n\nPair this with Speculation Rules (above) for instant + animated navigations.\n\n## Third-party scripts\n\n### Load strategies\n```javascript\n// ❌ Blocks main thread\n<script src=\"https://analytics.example.com/script.js\"></script>\n\n// ✅ Async loading\n<script async src=\"https://analytics.example.com/script.js\"></script>\n\n","tagline":"Optimize web performance for faster loading and better user experience.
