Especially NFS with blocking writes on large files.... Done badly, with the 
wrong file system I've seen servers disks trash continuously, and IO down at 
something resembling paper tape (well I exaggerate slightly).

Check the NFS time for copying larges files, compare to say FTP, NFS should be 
slower than FTP, but only says 20% slower....
