Performance Optimization

Resource Allocation

Tuning Recommendations

1. Limit concurrent sessions per user
2. Disable unused protocols (e.g., RDP if not needed)
3. Set session timeout thresholds
4. Allocate dedicated Docker resources:

# docker-compose.yml
services:
  nexus-terminal:
    deploy:
      resources:
        limits:
          cpus: '2'
          memory: 2G

Frequently Asked Questions

Q: Why does the terminal content copy fail?

A: Browser security restrictions require HTTPS for clipboard access. Solutions:

1. Deploy via HTTPS
2. Use localhost for testing
3. Enable Chrome flags for insecure contexts

Q: How to handle ARMv7 limitations?

A: ARMv7 builds exclude RDP support due to guacd compatibility. Workarounds:

• 🍄
  
  Use SSH tunneling for GUI access
• 🍄
  
  Consider upgrading to ARMv8 hardware
• 🍄
  
  Utilize the desktop client alternative

Q: Best practices for backups?

1. Regularly archive /nexus-terminal/data
2. Enable cloud sync for critical configurations
3. Use Docker volume mounts:

volumes:
  - ./data:/app/data
