Another consideration is if you don't like the rendering delay that will occur at the start of a render the first time one or more textures are used. And you prefer handle that one time process manually on your own term. Since 3Delight re-uses already optimized textures, subsequent renders will have no performance hit.

The Network Cache

3Delight has a unique feature that improves performance when rendering over networked environments: the renderer can cache textures that are located on the network to the local drive for faster data access and saving network bandwidth. The network cache content is updated automatically: when files are modified on the file server, the local (cached) copies will be automatically updated the first time they are needed for a rendering. If there is no more space in the cache,  copied textures are removed to make space for incoming textures by following the Least Recently Used (LRU) principle.
