Use when diagnosing slowness, improving load times, optimizing queries, reducing bundle size, or when asked about performance issues.\n---\n\n# Optimizing Performance\n\n### When to Load\n\n- **Trigger**: Diagnosing slowness, profiling, caching strategies, reducing load times, bundle size optimization\n- **Skip**: Correctness-focused work where performance is not a concern\n\n## Performance Optimization Workflow\n\nCopy this checklist and track progress:\n\n```\nPerformance Optimization Progress:\n- [ ] Step 1: Measure baseline performance\n- [ ] Step 2: Identify bottlenecks\n- [ ] Step 3: Apply targeted optimizations\n- [ ] Step 4: Measure again and compare\n- [ ] Step 5: Repeat if targets not met\n```\n\n**Critical Rule**: Never optimize without data. Always profile before and after changes.\n\n## Step 1: Measure Baseline\n\n### Profiling Commands\n\n```bash\n# Node.js profiling\nnode --prof app.js\nnode --prof-process isolate*.log > profile.txt\n\n# Python profiling\npython -m cProfile -o profile.stats app.py\npython -m pstats profile.stats\n\n# Web performance\nlighthouse https://example.com --output=json\n```\n\n## Step 2: Identify Bottlenecks\n\n### Common Bottleneck Categories\n\n| Category | Symptoms                         | Tools                           |\n| -------- | -------------------------------- | ------------------------------- |\n| CPU      | High CPU usage, slow computation | Profiler, flame graphs          |\n| Memory   | High RAM, GC pauses, OOM         | Heap snapshots, memory profiler |\n| I/O      | Slow disk/network, waiting       | strace, network inspector       |\n| Database | Slow queries, lock contention    | Query analyzer, EXPLAIN         |\n\n## Step 3: Apply Optimizations\n\n### Frontend Optimizations\n\n**Bundle Size:**\n\n```javascript\n// ❌ Import entire library\nimport _ from \"lodash\";\n\n// ✅ Import only needed functions\nimport debounce from \"lodash/debounce\";\n\n// ✅ Use dynamic imports for code splitting\nconst HeavyComponent = lazy(() => import(\"./HeavyComponent\"));\n```\n\n**Rendering:**\n\n```javascript\n// ❌ Render on every parent update\nfunction Child({ data }) {\n  return <ExpensiveComponent data={data} />;\n}\n\n// ✅ Memoize when props don't change\nconst Child = memo(function Child({ data }) {\n  return <ExpensiveComponent data={data} />;\n});\n\n// ✅ Use useMemo for expensive computations\nconst processed = useMemo(() => expensiveCalc(data), [data]);\n```\n\n**Images:**\n\n```html\n<!-- ❌ Unoptimized -->\n<img src=\"large-image.jpg\" />\n\n<!-- ✅ Optimized -->\n<img\n  src=\"image.webp\"\n  srcset=\"image-300.webp 300w, image-600.webp 600w\"\n  sizes=\"(max-width: 600px) 300px, 600px\"\n  loading=\"lazy\"\n  decoding=\"async\"\n/>\n```\n\n### Backend Optimizations\n\n**Database Queries:**\n\n```sql\n-- ❌ N+1 Query Problem\nSELECT * FROM users;\n-- Then for each user:\nSELECT * FROM orders WHERE user_id = ?;\n\n-- ✅ Single query with JOIN\nSELECT u.*, o.*\nFROM users u\nLEFT JOIN orders o ON u.id = o.user_id;\n\n-- ✅ Or use pagination\nSELECT * FROM users LIMIT 100 OFFSET 0;\n```\n\n**Caching Strategy:**\n\n```javascript\n// Multi-layer caching\nconst getUser = async (id) => {\n  // L1: In-memory cache (fastest)\n  let user = memoryCache.get(`user:${id}`);\n  if (user) return user;\n\n  // L2: Redis cache (fast)\n  user = await redis.get(`user:${id}`);\n  if (user) {\n    memoryCache.set(`user:${id}`, user, 60);\n    return JSON.parse(user);\n  }\n\n  // L3: Database (slow)\n  user = await db.users.findById(id);\n  await redis.setex(`user:${id}`, 3600, JSON.stringify(user));\n  memoryCache.set(`user:${id}`, user, 60);\n\n  return user;\n};\n```\n\n**Async Processing:**\n\n```javascript\n// ❌ Blocking operation\napp.post(\"/upload\", async (req, res) => {\n  await processVideo(req.file); // Takes 5 minutes\n  res.send(\"Done\");\n});\n\n// ✅ Queue for background processing\napp.post(\"/upload\", async (req, res) => {\n  const jobId = await queue.add(\"processVideo\", { file: req.file });\n  res.send({ jobId, status: \"processing\" });\n});\n```\n\n### Algorithm Optimizations\n\n```javascript\n// ❌ O(n²) - nested loops\nfunction findDuplicates(arr) {\n  const duplicates = [];\n  for (let i = 0; i < arr.length; i++) {\n    for (let j = i + 1; j < arr.length; j++) {\n      if (arr[i] === arr[j]) duplicates.push(arr[i]);\n    }\n  }\n  return duplicates;\n}\n\n// ✅ O(n) - hash map\nfunction findDuplicates(arr) {\n  const seen = new Set();\n  const duplicates = new Set();\n  for (const item of arr) {\n    if (seen.has(item)) duplicates.add(item);\n    seen.add(item);\n  }\n  return [...duplicates];\n}\n```\n\n## Step 4: Measure Again\n\nAfter applying optimizations, re-run profiling and compare:\n\n```\nComparison Checklist:\n- [ ] Run same profiling tools as baseline\n- [ ] Compare metrics before vs after\n- [ ] Verify no regressions in other areas\n- [ ] Document improvement percentages\n```\n\n## Performance Targets\n\n### Web Vitals\n\n| Metric | Good    | Needs Work | Poor    |\n| ------ | ------- | ---------- | ------- |\n| LCP    | < 2.5s  | 2.5-4s     | > 4s    |\n| INP    | < 200ms | 200-500ms  | > 500ms |\n| CLS    | < 0.1   | 0.1-0.25   | > 0.25  |\n| TTFB   | < 800ms | 800ms-1.8s | > 1.8s  |\n\n### API Performance\n\n| Metric      | Target  |\n| ----------- | ------- |\n| P50 Latency | < 100ms |\n| P95 Latency | < 500ms |\n| P99 Latency | < 1s    |\n| Error Rate  | < 0.1%  |\n\n## Validation\n\nAfter optimization, validate results:\n\n```\nPerformance Validation:\n- [ ] Metrics improved from baseline\n- [ ] No functionality regressions\n- [ ] No new errors introduced\n- [ ] Changes are sustainable (not one-time fixes)\n- [ ] Performance gains documented\n```\n\nIf targets not met, return to Step 2 and identify remaining bottlenecks.\n","tagline":"Analyzes and optimizes application performance across frontend, backend, and database layers.
