Goal: Provide concrete performance data to justify switching from competitors

Competitors to Benchmark:

• cross-spawn (102M downloads) - process spawning
• execa (98M downloads) - modern process execution
• ShellJS (9M downloads) - built-in commands
• zx (Google) - shell scripting
• Bun.$ (built-in) - native performance

Benchmark Categories:

1. Bundle Size:

• Our ~20KB vs competitors' 2KB-400KB+
• Tree-shaking effectiveness
• Runtime memory usage

2. Performance:

• Process spawning speed
• Streaming vs buffering throughput
• Built-in commands vs system calls
• Pipeline performance

3. Feature Completeness:

• API compatibility tests
• Migration path validation
• Feature parity verification

4. Real-world Use Cases:

• CI/CD script performance
• Log processing throughput
• File operations speed
• Network command handling

Implementation:

• Automated benchmark suite
• CI integration for regression testing
• Comparison charts and graphs
• Interactive benchmark playground
• Documentation with results

Success Metrics:
