Node.js provides built-in performance hooks and measurement APIs to help identify and address performance bottlenecks in applications. By using these tools, developers can achieve higher precision in measuring execution times, mark key events in the code, and use Prometheus for exporting performance data. The post covers methods like performance.now, performance.mark, and performance.measure for comprehensive performance monitoring, and provides examples of optimizing database queries and sorting algorithms. It also introduces the use of worker threads for offloading computationally intensive tasks without blocking the main thread.
