+**NOTE**: As of LiteSpeed Web Server v5.4, the **Reuse Port Listener** feature allows LSWS to use multiple cores automatically without any extra configuration, unless the feature is disabled.
+The following documentation pertains only to versions prior to v5.4, which are not equipped with the **Reuse Port Listener** feature.
 ===== Setup to use multicores =====
-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.

-The error message simply means the ssl is not configured through WebAdmin ( which is actually true, since LSWS will use apache ssl configuration) and Apache config will fill in the SSL cert.  The error message can be safely ignored as long as SSL is working fine.
