Connection Pool Performance Benchmark
=====================================

Comprehensive benchmark for validating connection pool improvements:
- Socket.IO connection reliability and performance
- Connection pooling effectiveness
- Error rate reduction validation
- Concurrent connection handling

Target: 40-60% reduction in connection errors through pooling
