There are multiple Multi-Processing Modules to pick from, but which should I pick? Are there drawbacks to picking a different one?
Our default profile uses Prefork for mod_ruid2, but you may prefer to use Worker or Event.
If you want to use Event, it is necessary to customize your profile because the standard ones we provide do not include it. Feel free to change your MPM, but see What's the importance of running scripts as the user? when uninstalling mod_ruid2.
