Agreed. And it's not just a BFS or OpenVM thing, it is the nature of NFS: not best for bulk transfer.
For bulk transfer, you can use FTP (pleh!) directly to/from CMS or you can rsync or scp with a Linux guest which plays PUN/RDR with CMS land. -- R; <>< On Thu, Oct 15, 2009 at 12:56, Gentry, Stephen <[email protected]> wrote: > I'd like to mention a caveat.
