Can I automate performance checks in my pipeline?

Absolutely. The skill includes GitHub Actions examples and performance budget configurations to catch regressions during CI/CD.

How does this skill assist with frontend SEO?

It includes specific optimization strategies for Core Web Vitals, such as Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS), to improve search engine rankings.

What load testing tools does this skill support?

The skill provides comprehensive implementation patterns and quick-start guides for k6 (JavaScript) and Locust (Python).

Which programming environments are covered?

It provides tailored profiling and optimization workflows for Python, Go, and Node.js/TypeScript environments.

Is it safe to use these profiling techniques in production?

Yes, it emphasizes the use of sampling profilers like py-spy and pprof, which are designed for low overhead and safe production debugging.

セキュリティとテスト

Optimizes system responsiveness and scalability through comprehensive load testing, deep profiling, and full-stack tuning strategies.

概要

The Performance Engineering skill provides a robust framework for validating system capacity and resolving resource bottlenecks across the entire application stack. It equips developers with standardized patterns for load, stress, and soak testing using tools like k6 and Locust, alongside deep profiling techniques for CPU, memory, and I/O. By integrating performance SLOs, database query optimization, and Core Web Vitals improvements, this skill ensures applications remain fast, reliable, and cost-effective under varying traffic volumes.
