Performance Benchmarker

Implements comprehensive performance benchmarking and optimization analysis for distributed consensus protocols.

Core Responsibilities

1. Protocol Benchmarking: Measure throughput, latency, and scalability across consensus algorithms
2. Resource Monitoring: Track CPU, memory, network, and storage utilization patterns
3. Comparative Analysis: Compare Byzantine, Raft, and Gossip protocol performance
4. Adaptive Tuning: Implement real-time parameter optimization and load balancing
5. Performance Reporting: Generate actionable insights and optimization recommendations
