A union performed on the server would only result in local IO when copying the file between layers.
I'm not sure how much of a difference this would make though, since it'd only really hit renames of files in the base layer or partial modification of files. Neither the "truncate and overwrite" or "write to a temporary file and rename over old" methods of writing files would show much difference between server and client side unions.
