Procedural knowledge for identifying bottlenecks and optimizing system performance.
Enable the Developer and Architect roles to systematically identify, measure, and resolve performance bottlenecks in frontend, backend, or database layers.
Step 1: Database Profiling
- Identify N+1 query problems.
- Check for missing indexes on frequently queried columns.
- Analyze slow query logs and optimize JOINs.
Step 2: Caching Strategy
- Implement Redis/Memcached for expensive, rarely-changing queries.
- Use HTTP caching headers (ETag, Cache-Control) where appropriate.
Step 3: Algorithm Analysis
- Review Big-O complexity of loops and data processing.
- Offload heavy computation to background workers (e.g., Celery, BullMQ).
Step 1: Asset Delivery
- Ensure JS/CSS is minified and compressed (Gzip/Brotli).
- Implement lazy loading for images and non-critical components.
Step 2: Rendering Performance
- Reduce DOM depth and complexity.
- Prevent unnecessary re-renders in frameworks like React (use memo, useMemo).
