Node.js Performance Tuning & Profiling

Deep performance optimization for Node.js applications: event loop analysis, memory leak detection, concurrency tuning, and scalability architecture review.

• Event loop delay monitoring & troubleshooting
• Memory profiling & leak detection
• CPU & I/O bottleneck analysis
• Cluster & worker threads optimization
• Garbage collection tuning

• Improve request throughput by 3–5x
• Reduce latency p99 by 60%
• Lower cloud compute costs (fewer instances)
• Prevent runtime crashes in production
