Autoconfig
Even if you are an expert user it is recommended to start with Autoconfig. You can start Autoconfig in Setup wizart after you activated Swift Performance at the first time, but you can also run it again from the top bar menu.
Autoconfig will detect the environment, theme, plugins and will configure Swift Performance automatically. Once the process has been finished, you can tweak settings manually to get the best achievable results.
