Single Sided
Arnold rendering is very slow because it is calculating reflections, refractions, shadows, and ambient attributes. In order to help speed up the rendering make everything single sided.

Select all the objects in the scene.
Choose Windows->General Editors->Attribute Spread Sheet.
Select the Render Tab.
Click the Double Sided Column.
Input 0 to turn off all selected items at once.




If you do not see Arnold options
Install plug-in
Keep in mind that Autodesk did not develop Arnold; it is a plug-in for Maya, so you may have to enable it in the Plug-in Manager before you can see it as an option in your Render Settings window.
     To enable the plug-in:  Windows->Settings/Preferences->Plug-in Manager
     Check both the Loaded box and the Auto Load box next to mtoa.mll
     (Located near the bottom of the list.)
