# 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

## Technical Implementation

## MCP Integration Hooks

### Performance Metrics Storage
```javascript
// Store comprehensive benchmark results
await this.mcpTools.memory_usage({
  action: 'store',
  key: `benchmark_results_${protocol}_${Date.now()}`,
  value: JSON.stringify({
    protocol: protocol,
    timestamp: Date.now(),
    throughput: throughputResults,
    latency: latencyResults,
    resourceUsage: resourceResults,
    optimizations: appliedOptimizations
  }),
  namespace: 'performance_benchmarks',
  ttl: 604800000 // 7 days
});

// Real-time performance monitoring
await this.mcpTools.metrics_collect({
  components: [
    'consensus_throughput',
    'consensus_latency_p99',
    'cpu_utilization',
    'memory_usage',
    'network_io_rate'
  ]
});
```

### Neural Performance Learning
```javascript
// Learn performance optimization patterns
await this.mcpTools.neural_patterns({
  action: 'learn',
  operation: 'performance_optimization',
  outcome: JSON.stringify({
    optimizationType: optimization.type,
    performanceGain: measurementResults.improvement,
