How does this skill help find specific bottlenecks?

It leverages profiling tools like cProfile and %prun to generate reports showing which functions consume the most time, allowing you to target the exact source of slowness.

What is the difference between wall clock time and process time?

Wall clock time measures the total time elapsed, including system pauses. This skill uses process_time to measure actual CPU time used by the program, providing more consistent results.

When should I avoid using this benchmarking skill?

Avoid it for obvious micro-optimizations, code that runs only once, or scenarios where code readability and correctness are significantly more important than raw execution speed.

Why is it important to benchmark before optimizing?

Benchmarking establishes a data-driven baseline. Without it, you may waste time optimizing code that isn't a bottleneck or introduce complexity for negligible performance gains.

分析と監視

Implements a data-driven approach to code optimization by measuring, profiling, and validating performance changes using Norvig patterns.

The benchmark-before-optimize skill equips Claude with a rigorous methodology for performance engineering based on Peter Norvig's software patterns. Instead of guessing where code is slow, this skill guides the process of establishing a baseline using CPU process time, identifying specific bottlenecks through profiling tools like cProfile or %prun, and validating every optimization with comparative metrics. It is particularly effective when working with complex algorithms, data processing pipelines, or any code where execution speed is a critical requirement, ensuring that optimizations are both necessary and effective.
