Performance Benchmarks

Detailed performance analysis demonstrating aspect-rs overhead.

Key Findings

• Empty function: +2ns overhead (20%)
• Logging aspect: +2ns overhead (13%)
• Timing aspect: +2ns overhead (10%)
• Caching aspect (hit): +2ns overhead (40%)
• Caching aspect (miss): +2ns overhead (2%)

Conclusion: aspect-rs has consistent ~2ns overhead regardless of function complexity.
