Performance Optimization Skill

Master Node.js performance optimization for fast, scalable, and efficient backend applications.

Quick Start

Optimize in 4 areas:

1. Caching - Redis/in-memory caching
2. Clustering - Use all CPU cores
3. Profiling - Find bottlenecks
4. Monitoring - Track performance

Core Concepts

Caching with Redis

const redis = require('redis');
const client = redis.createClient({ url: process.env.REDIS_URL });
