-fdpi_ctrl uses ordinary linux stack to communicat with the dpi, so the tuning recommendations is similar to the high load web servers (nginx-like) \\
-Settings are similar to the nginx. It is recommended to insert it /etc/sysctl.conf (to keep safe from being droped after server restart)\\

-To avoid rebooting the server they can be modified on-the-fly by applying the command:
-sysctl -w настройка, например, sysctl -w net.ipv4.tcp_tw_reuse=1\\
-This should do the trick\\
