/**
* LiveComponent Performance Benchmarks
*
* Benchmarks for Fragment vs Full Render and Batch vs Individual Requests.
* Validates the performance claims made in Phase 2 documentation.
*
* Expected Performance Improvements:
* - Fragment Updates: 60-90% bandwidth reduction
* - Fragment Updates: 70-95% fewer DOM operations
* - Request Batching: 60-80% fewer HTTP requests
* - Request Batching: ~40% reduction in total bytes transferred
