Peter,

I think you will find that if the copy is run
on the fileserver itself then the loopback
address is used (eg data does not flow
"across the wire"). This is a special
case because I would normally expect
only system administrators to have
access to the fileserver.

Have you thought of using a symbolic link
instead of copying the file?

I believe AFS was not designed to optimise 500 MB file copying
from a client machine but it does provide a scalable secure
distributed filesystem.
