examples:
  - input: "Function profiling for data processing"
    output: "Time: 145ms, CPU: 32.5%, Memory: 12.4MB"
  - input: "Detect bottlenecks in database queries"
    output: "N+1 query pattern found, missing index on user_id"
  - input: "Analyze caching for user session data"
    output: "LRU cache recommended, 85% hit rate expected"
  - input: "Load test with 100 concurrent users"
    output: "Throughput: 425 req/s, P99 latency: 892ms"

success_criteria:
  - Identified performance bottlenecks with 90%+ accuracy
  - Profiling overhead < 5% of execution time
  - Cache strategy recommendations improve hit rate by 20%+
  - Load test simulation realistic within 15% variance

integration_points:
  - Code Refactoring Advisor (code quality metrics)
  - Database Operations Manager (query optimization)
  - Security Vulnerability Scanner (performance security)
  - API Integration Helper (endpoint monitoring)

notes: |
  Performance Optimization provides enterprise-grade performance analysis and optimization capabilities:
