SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps identify and resolve performance bottlenecks in your code by providing tools and techniques for CPU and memory profiling, and guiding you through benchmark analysis.

Core Features & Use Cases

  • CPU Profiling: Analyze JavaScript/Node.js and Python code execution to pinpoint time-consuming functions.
  • Memory Leak Detection: Identify and fix memory leaks in applications.
  • Benchmarking: Measure the performance of different code implementations and optimize them.
  • Database Profiling: Analyze slow queries in PostgreSQL and MongoDB.
  • Use Case: Your Node.js application is experiencing high CPU usage. Use this Skill to profile the application, identify the functions consuming the most CPU time, and implement optimizations.

Quick Start

Use the performance_profiling skill to analyze the CPU usage of your Node.js application by running npx clinic doctor -- node app.js.
