High Traffic Server Settings on RHEL / AlmaLinux / Rocky / EuroLinux / CentOS 8

High Traffic Server Settings on RHEL / AlmaLinux / Rocky / EuroLinux / CentOS 8

I recently did some work to optimize the network configuration of an AlmaLinux 8 based web server that receives a lot of traffic.

Of course these settings also apply to RHEL / Rocky / EuroLinux / CentOS 8 (hereafter referred to as Linux 8.) I think these should also work on RHEL / AlmaLinux / Rocky / EuroLinux 9 as well but I have not yet tested them.

There is a lot of information on the web for this and it distills down to a minimum recommended configuration, and a recommended configuration.

The minimum recommended configuration should be sufficient for servers with less than 10Gb, and the recommended configuration should be sufficient for servers with 10Gb or more.
