Optimizing Server

What steps should I take to optimize my server so it can load http as fast as possible? I just got a dedicated server yesterday, I have no idea how to use linux, so far I have done everything through Cpanel. So, if you could tell me what I need to change in the config files and HOW to change them so that my server can run as fast as possible, please tell me. Thank you.
