# Performance Benchmarking Report - Goal 3 Task 4

## Benchmarking Methodology

### CLI Interface Testing
- **Tools**: Custom Python benchmarking script (`cli_benchmark.py`)
- **Metrics**:
  - Response time (ms)
  - Throughput (requests/second)
  - Security overhead impact (RBAC, TLS 1.3)
- **Test Cases**:
  - Single-threaded execution
  - Concurrent execution (10 threads)
- **Target**: <500ms response time

### Web Interface Testing  
- **Tools**: Custom Python benchmarking script (`web_benchmark.py`)
- **Metrics**:
  - Response time (ms)
  - Throughput (requests/second) 
  - Security overhead impact (RBAC, TLS 1.3)
- **Test Cases**:
  - Single-threaded execution
  - Concurrent execution (10 threads)
- **Target**: <500ms response time

## Security Requirements
```markdown
## Security Requirements (from symphony-core.md)

1. **Encryption**: All secrets must use AES-256 encryption
2. **Access Control**: RBAC required for privileged operations
3. **Audit Logging**:
   - Logs retained for 90 days
   - Integrity protection (HMAC-SHA256)
4. **Transport Security**:
   - TLS 1.3 enforced
   - Modern ciphers (AES256-GCM, CHACHA20)
   - MCP client certificate pinning (SHA-256 fingerprints)
5. **Performance Targets**:
   - API Response Time ≤ 800ms (with security overhead)
   - Memory Footprint ≤ 512MB

## Performance Benchmarks (from test_performance.py)

### Event Processing
- **Throughput**: Minimum 100 events/sec (test_event_throughput)
- **Concurrency**: Supports 10 concurrent publishers (test_concurrent_publishers)
- **Latency**:
  - Immediate events: <500ms response time
  - Scheduled events: <1.5s for 100 events with 10ms delay (test_scheduled_events)

### Test Methodology
1. **Throughput Test**:
   - Publishes 1000 events sequentially
   - Measures total processing time
   - Verifies ≥100 events/sec rate

2. **Concurrency Test**:
   - 10 threads each publishing 100 events
   - Verifies thread safety and consistent throughput

3. **Scheduled Events Test**:
   - Schedules 100 events with 10ms delay
   - Verifies all events processed within 1.5s
```

  }
}
```

## Analysis Framework
1. **Performance Baseline**:
   - Compare against <500ms target
   - Identify bottlenecks

2. **Security Impact**:
   - Measure RBAC overhead
   - Measure TLS 1.3 overhead
   - Compare combined security impact

3. **Concurrency Scaling**:
   - Evaluate throughput under load
   - Identify contention points

4. **Recommendations**:
   - Optimization opportunities
   - Configuration adjustments
   - Architectural improvements

## Execution Plan
1. Run CLI benchmarks
2. Run Web benchmarks  
3. Generate performance_logs.json
4. Analyze results
5. Document findings
6. Submit for review
