	My understanding of the hard disk throughput problem is OS related, not
driver related. From what I have heard, even DMA hard disks suffer greatly from
this problem. NFS being a DOS device, would only share in this headache. The
bottome line is, NFS can't run faster than a hard disk, bandwidth asside.
Am I wrong?
