Depends on the number of themes and whether or not you are using a database or a file based-datasource. For a layer that has a lot of themes, I have found that having multiple layers from an exploded theme has MUCH better performance when using MS-SQL as the backend.

(Assuming all exploded layers are turned on compared to the single themed layer.)
