What problem does it solve?

Go benchmarking often lacks consistent patterns and repeatable measurement. This Skill provides a structured approach to writing and analyzing Go benchmarks using contemporary loops and benchstat.

Core Features & Use Cases

• Loop-based benchmarking: Use b.Loop() for reliable timing and to avoid compiler optimizations.
• Incremental experimentation: Compare baseline and changes to understand impact using benchstat.
• Profiling guidance: Includes CPU/memory profiling workflows and how to interpret results to guide optimizations.
• Real-world scenario: Normalize results across variations in data sizes and setups to inform performance decisions.

Quick Start

Run a baseline benchmark to establish a performance reference and compare subsequent changes using benchstat.
