Performance Optimization

Optimize your DÆTA node's network and storage settings for maximum performance, ensuring efficient operations and improved security.

Network Optimization

1. Configure Firewall

Allow necessary ports:

sudo ufw allow 28967/tcp
sudo ufw allow 28967/udp
sudo ufw allow 9000/tcp

2. Optimize TCP Settings

Add to /etc/sysctl.conf:

net.core.rmem_max = 4194304
net.core.wmem_max = 4194304
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096 65536 4194304

Apply changes:

sudo sysctl -p

3. Use a Content Delivery Network (CDN)

Configure Cloudflare or similar CDN to proxy traffic to your node for improved performance and DDoS protection.

Storage Optimization

1. Use High-Performance SSDs

NVMe SSDs are recommended for optimal I/O performance.

2. Implement RAID

For improved reliability and performance, consider RAID 10 configuration:

sudo mdadm --create /dev/md0 --level=10 --raid-devices=4 /dev/sda /dev/sdb /dev/sdc /dev/sdd

3. File System Tuning

For ext4 file system, adjust mount options in /etc/fstab:

UUID=your-uuid /mnt/data ext4 defaults,noatime,nodiratime,discard 0 0

Resource Management

1. Monitoring with Prometheus and Grafana

Install Prometheus:

sudo apt install -y prometheus

Configure Prometheus to scrape your node metrics by adding to /etc/prometheus/prometheus.yml:

scrape_configs:
  - job_name: 'daeta_node'
    static_configs:
      - targets: ['localhost:9000']

2. Set Resource Limits

Create a systemd override file:

sudo systemctl edit daeta-node

Add the following:

[Service]
CPUQuota=800%
MemoryMax=14G

This limits the node to 8 CPU cores and 14GB of RAM.

Troubleshooting

Common Issue and Solutions

1. Node Not Syncing

Check network connectivity:

daeta-node network test

Ensure ports are open:

nc -zv satellite.daeta.io 7777

2. Low Earnings

Verify storage allocation:

daeta-node storage info

Check reputation score:

daeta-node reputation

3. High Resource Usage

Monitor resource usage:

top -c -p $(pgrep -d',' -f daeta-node)

Adjust resource limits as needed.

4. Failed Audits

Check disk health:

sudo smartctl -a /dev/sda

Verify data integrity:

daeta-node audit test

Loggind and Debugging

1. View Logs

journalctl -u daeta-node -f

2. Enable Debug Logging

Edit /etc/daeta/config.yaml:

debug:
  level: "debug"
  log_path: "/var/log/daeta-debug.log"

3. Analyze Logs

Use log analysis tools like lnav for better insights:

sudo apt install lnav
lnav /var/log/daeta-debug.log

Best Practices

1. Regular Maintenance

Schedule weekly system updates.

Perform monthly disk health checks.

2. Security

Use SSH key-based authentication.

Implement fail2ban for brute-force protection.

Keep the node software up-to-date.

3. Redundancy

Set up RAID for storage redundancy.

Consider running multiple nodes in different locations.

4. Community Engagement

Join the DÆTA Discord.

Participate in network stress tests and challenges.

5. Performance Monitoring

Set up alerts for disk space, CPU usage and bandwidth consumption.

Regularly review and optimize based on performance metrics.

By following these guidelines and best practices, node operators can ensure optimal performance, maximize earnings and contribute to the overall health and reliability of the DÆTA network.
