Mastering Node.js Performance Optimization

Understanding Node.js Performance

Node.js performance optimization is crucial for building scalable backend applications. This guide covers the most important techniques and strategies.

Memory Management

Proper memory management prevents memory leaks and improves application performance:

• Monitor memory usage with tools like clinic.js
• Avoid memory leaks in event listeners
• Use streaming for large data processing

Event Loop Optimization

The event loop is the heart of Node.js. Understanding and optimizing it is key to performance.

Clustering and Load Balancing

Utilize all CPU cores with clustering and implement proper load balancing strategies for maximum throughput.
