Not necessarily slower: coreutils has fast implementation (maybe, even
faster that Emacs' own), and calling external process causes no big overhead.

But advantages of using external commands are numerous: they are rich of
features whose reimplementation in Emacs doesn't sound reasonable.

Please note that I don't propose replacing existing Emacs implementation
of basic copy and move operations by external commands.  I propose using
external commands only for functionality not available in Emacs, like
cross-partition move or `cp -u'.
