Learning Outline

• 1. Rule Profiling — `--profiling` flag to identify slow rules
• 2. String Optimization — Cheap strings first, expensive regexes last
• 3. Regular Expression Performance — Avoiding catastrophic backtracking
• 4. Module Usage Impact — PE/ELF module costs
• 5. File Size Filtering — Skipping large files with `filesize`
• 6. Threading — `-p` flag for parallel scanning
• 7. Compiled Rules — Using `yarac` for faster loading
• 8. Memory Usage — Monitoring and reducing memory footprint
• 9. Distributed Scanning — Scaling across multiple cores/servers
• 10. Benchmarking — Comparing rule set performance
