 - Disable the application types you do not want to deal with
 - If you don't care about restarting the app every time a new supported package technology is installed, enable `single_dependency_checking`. This can reduce the application response time, since it won't need to recheck if the required technologies are available on your system every time a given action is executed.
 - If you don't mind to see the applications icons, you can disable them via `download: icons: false`. The application may have a slight response improvement, since it will reduce the IO and parallelism within it.
+- For a faster initialization process, consider raising the values of settings properties associated with disk caching.
