In some cases, you may want to know more about what steps you can take to optimize website loading times, and overall server performance.
Please note that while you can take action to alter how your server functions, the optimization of the server's performance is not something that cPanel manages or controls directly. In general, server optimization requires a lot of in-depth investigation into your server's needs and is best handled by a Systems Administrator or Hosting Provider.
Server optimization covers a vast amount of topics that can cover almost every aspect of the server, however, I have listed guides I find helpful, that cover the most common issues I see users experience.
As long as your server has enough hardware to balance out its active workload, proper utilization and implementation of the above guides can help you get more performance out of your server.
