How to Use More Cores With a 2-CPU or Above License on cPanel

You can boost your website's benchmark performance by selecting a higher-CPU license. If you have a 2-CPU or above license on cPanel, you can check how many LiteSpeed processes are running in “top”. Sometimes you may only see one core being used by LiteSpeed processes. Why?

Websites configured via Apache configuration, such as in a cPanel environment, are served by one CPU by default. You can add a listener for a site's <IP : Port> in LiteSpeed's native configuration. Bind it to two processes to fully utilize the 2-CPU license (or more) in your benchmark test.

The following shows how to enable two processes for your website for port 80. Select the IP that is used by your benchmark-testing domain associated with the virtual host.

You can also enable processes for port 443 for https. In this case, no need to setup ssl part since LSWS will use the one configured by control panel apache virtual host.

It is normal that manually created listener(s) will not show in running in such control panel environment.
