Node.js Performance Optimization Techniques
Node.js handles thousands of concurrent connections efficiently, but poor code can still cause performance bottlenecks. Event Loop Blocking: CPU-intensive operations block the event loop. Offload heavy computation to worker threads or child processes. Memory Leaks: Common sources include global variables, forgotten timers, and closures holding references. Use --inspect for heap snapshots. Database Optimization: Use connection pooling, index frequently queried fields, avoid N+1 queries, and use caching (Redis) for hot data....
