# 📈 Performance & Scaling Guide ## Benchmarks ### Single IOC Analysis - **Average Response Time**: ~2-5 seconds - **Peak Throughput**: ~500 IOCs/minute - **Memory Usage**: <100MB for typical workloads - **Cache Hit Rate**: >90% in production environments ### Batch Processing Performance - **Small Batches (1-10 IOCs)**: ~3-8 seconds - **Medium Batches (10-100 IOCs)**: ~30-120 seconds - **Large Batches (100-1000 IOCs)**: ~5-20 minutes ## Optimization Strategies ### 1. Caching Configuration ```bash # Optimal cache settings for production CACHE_TTL=7200 # 2 hours for most IOCs MAX_RETRIES=5 # Increased retries for reliability REQUEST_TIMEOUT=45 # Longer timeout for batch operations ``` ### 2. API Rate Limiting ```python # Configure rate limiting for different services VIRUSTOTAL_RATE_LIMIT=4 # requests per minute (free tier) OTX_RATE_LIMIT=1000 # requests per hour ABUSEIPDB_RATE_LIMIT=1000 # requests per day ``` ### 3. Memory Optimization ```bash # For large batch processing PYTHON_OPTS="-O -W ignore" # Optimize Python execution MAX_WORKERS=4 # Limit concurrent workers BATCH_SIZE=50 # Process in smaller chunks ``` ## Production Deployment ### Docker Compose Production Setup ```yaml # docker-compose.prod.yml version: '3.8' services: threatintel: image: arjuntrivedi/4r9un:fastmcp-threatintel-latest restart: unless-stopped environment: - VIRUSTOTAL_API_KEY=${VIRUSTOTAL_API_KEY} - OTX_API_KEY=${OTX_API_KEY} - ABUSEIPDB_API_KEY=${ABUSEIPDB_API_KEY} - IPINFO_API_KEY=${IPINFO_API_KEY} - CACHE_TTL=7200 - MAX_RETRIES=5 - REQUEST_TIMEOUT=45 volumes: - ./reports:/app/reports - ./cache:/app/cache ports: - "8000:8000" healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8000/health"] interval: 30s timeout: 10s retries: 3 deploy: resources: limits: memory: 512M reservations: memory: 256M ``` ### Kubernetes Deployment ```yaml # k8s-deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: fastmcp-threatintel spec: replicas: 3 selector: matchLabels: app: fastmcp-threatintel template: metadata: labels: app: fastmcp-threatintel spec: containers: - name: threatintel image: arjuntrivedi/4r9un:fastmcp-threatintel-latest ports: - containerPort: 8000 env: - name: VIRUSTOTAL_API_KEY valueFrom: secretKeyRef: name: threatintel-secrets key: virustotal-key resources: limits: memory: "512Mi" cpu: "500m" requests: memory: "256Mi" cpu: "250m" livenessProbe: httpGet: path: /health port: 8000 initialDelaySeconds: 30 periodSeconds: 10 ``` ## Monitoring & Metrics ### Application Metrics ```python # Add to your monitoring setup import time import logging from functools import wraps def monitor_performance(func): @wraps(func) async def wrapper(*args, **kwargs): start_time = time.time() try: result = await func(*args, **kwargs) duration = time.time() - start_time logging.info(f"{func.__name__} completed in {duration:.2f}s") return result except Exception as e: duration = time.time() - start_time logging.error(f"{func.__name__} failed after {duration:.2f}s: {e}") raise return wrapper ``` ### Log Analysis ```bash # Analyze performance logs grep "completed in" /var/log/threatintel.log | awk '{print $NF}' | sort -n # Monitor error rates grep "ERROR" /var/log/threatintel.log | wc -l # Track API usage grep "API_CALL" /var/log/threatintel.log | cut -d' ' -f3 | sort | uniq -c ``` ## Scaling Recommendations ### Horizontal Scaling - **Load Balancer**: Use NGINX or HAProxy for request distribution - **Multiple Instances**: Deploy 3-5 instances behind load balancer - **Database**: Consider Redis for shared caching across instances ### Vertical Scaling - **CPU**: 2-4 cores recommended for production - **Memory**: 1-2GB RAM for typical workloads - **Storage**: SSD recommended for cache and reports ### API Key Distribution - **Multiple Keys**: Use different API keys across instances - **Key Rotation**: Implement automatic key rotation - **Rate Limiting**: Implement per-key rate limiting ## Troubleshooting Performance Issues ### Common Bottlenecks 1. **API Rate Limits** ```bash # Check for rate limit errors grep "rate limit" /var/log/threatintel.log ``` 2. **Network Latency** ```bash # Test API response times curl -w "%{time_total}\n" -o /dev/null -s "https://www.virustotal.com/vtapi/v2/file/report" ``` 3. **Memory Issues** ```bash # Monitor memory usage docker stats fastmcp-threatintel ``` ### Performance Tuning 1. **Increase Cache TTL** ```bash export CACHE_TTL=14400 # 4 hours ``` 2. **Optimize Batch Size** ```python # Process in smaller chunks OPTIMAL_BATCH_SIZE = 25 ``` 3. **Enable Compression** ```bash export COMPRESS_RESPONSES=true ``` ## Best Practices 1. **Cache Warming**: Pre-populate cache with common IOCs 2. **Graceful Degradation**: Continue with partial results if some APIs fail 3. **Circuit Breaker**: Implement circuit breaker pattern for API calls 4. **Async Processing**: Use async/await for all I/O operations 5. **Connection Pooling**: Reuse HTTP connections for better performance
