# Same File Multiple Renders

While uploading the render ‘package’ (.duf file and enhancement elements) for the first time - and as long as you remain connected to the same active session - Boost for Daz enhances an intelligent caching feature in Iray Server that automatically creates a temporary cache in the cloud of the entire package for you. So after you view your first completed render and you go back and make changes to your Daz project and hit ‘render’ again, only the updates are collected in a smaller ‘package’ and sent up to the active Iray Server session on Boost for Daz. The updates and all the previous files and elements (now stored in this temporary cache) are used to create your new render output. So as long as you are connected to the same Iray server session on Boost for Daz, the second and all subsequent renders will take significantly less time. As soon as you sign out, that session is disassembled and all temporary caches are deleted (ephemeral).
