Server performance optimizations for Odoo

Server Tuning & Optimization

a. Adjust Swappiness

Lower the swappiness value to improve system performance:

sudo echo "vm.swappiness = 5" >> /etc/sysctl.conf &&
sudo sysctl -p && sudo swapoff -a && sudo swapon -a

b. Set Up ZRAM

Improve memory utilization by compressing swap in RAM:

sudo apt install -y -f zram-tools &&
sudo echo "ALGO=lz4" >> /etc/default/zramswap &&
sudo echo "PERCENT=30" >> /etc/default/zramswap &&
sudo echo "PRIORITY=1" >> /etc/default/zramswap &&
sudo systemctl restart zramswap.service && sudo systemctl enable zramswap.service

c. Configure the Firewall

Secure your server by allowing SSH and NGINX traffic:

sudo apt install -y -f ufw &&
sudo ufw allow ssh &&
sudo ufw allow 'Nginx Full' &&
sudo ufw delete allow 'Nginx HTTP' &&
sudo ufw --force enable && sudo ufw reload && sudo ufw status

d. Clean Temporary Files

Set up a cron job to periodically delete temporary files:

(crontab -l 2>/dev/null; echo "0 */12 * * * sudo find /tmp -type f -atime +1 -delete") | crontab -

e. Tune System Performance

Apply a high-throughput profile with the tuned utility:

sudo apt install -y -f tuned &&
sudo tuned-adm profile throughput-performance &&
sudo tuned-adm active &&
sudo systemctl restart tuned.service && sudo systemctl enable tuned.service
