It's on the client. Most of our mirrors prefer not running any code on
the server.
If it's the client, that really doesn't cut down on
bandwidth because the client would have to d/l the new package to diff
it against the old one (and if it didn't have the old one, d/l it
too).
It doesn't need to download the old one too. See

"It's on the client", doesn't appear to be correct!
The diff-rpm must be generated on a server (somewhere) and pushed to
the mirrors along with the full-rpm. The mirror servers don't run any
special code, they just host the full-rpms and the diff-rpms.
The client gets the diff-rpm and constructs the full-rpm using the
diff-rpm and the previous full-rpm (which has to be saved on the client).
