/optimize-perf

Analyze and optimize code for runtime performance with measurable improvements.

Steps

1. Identify the performance target: 2. Profile the code: 3. Analyze common performance issues: 4. Apply optimizations in order of impact: 5. Measure the improvement after each optimization. 6. Document the trade-offs of each optimization.

Format

Target: <what was optimized>
Before: <baseline metric>
After: <improved metric>
Improvement: <percentage>

Rules

• Always measure before and after; never optimize without data.
• Fix the biggest bottleneck first (Amdahl's Law).
• Do not sacrifice readability for marginal gains.
