performance-profiling skillA

Name: performance-profiling
Author: fabioc-aloha

performance-profiling is agent-read markdown (skill) from fabioc-aloha/alex_skill_mall: CPU, memory, network bottleneck analysis — systematic performance investigation.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# Performance Profiling Skill

> Find the bottleneck before optimizing. Measure twice, optimize once.

## The Golden Rule

But also:
