System Optimization

System Optimization #

The operating system of the server where INFINI Gateway is installed needs to be optimized to ensure that INFINI Gateway runs in the best possible state. The following uses Linux as an example.

System Parameters #

sudo tee /etc/security/limits.d/21-infini.conf <<-'EOF'
*                soft    nofile         2100000
*                hard    nofile         2100000
*                soft    memlock        unlimited
*                hard    memlock        unlimited

SETTINGS

Run the following command to check whether configuration parameters are valid.

sysctl -p

Restart the operating system to make the configuration take effect.
