 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.

 +===== Troubleshooting =====
 +==== Full Stop/Start ====
 +If you see ''​failed to create new listener'',​
 +  2019-03-07 11:​17:​32.583428 ​   ERROR    HttpListener::​start():​ Can’t listen at address https: Address already in use!
 +  2019-03-07 11:​17:​32.583462 ​   ERROR    HttpServer::​addListener(https) failed to create new listener
 +  2019-03-07 11:​17:​32.583471 ​   ERROR    [config:​server:​listener:​https] failed to start listener on address *:443!
 +
 +most likely you ran a graceful restart. You should bring the server to a full stop, and run a full restart to make the setting effective. Like so:
 +
 +  service lsws stop
 +  service lsws start
 +  ​
 +==== Failed to Create SSL Context for Listener ====
 +Even if you run a full stop then a full start, you may see the following warning message:
 +  LEVEL: WARN [config:​server:​listener:​https] failed to create SSL context for listener 208.75.148.57:​443,​ turn SSL off.
 + 
 +Verify that you can browse to the domain successfully. Use the ''​top''​ command to check that LiteSpeed processes are sharing CPU equally without any issue.
 +
 +The error message simply means the SSL is not configured through WebAdmin (which is actually true, since LSWS will use Apache'​s SSL configuration) and that the Apache configuration will fill in the SSL certificate. ​ The error message can be safely ignored as long as SSL is working fine.    ​
