We have a few PC's connected via thin ethernet to a Sun 3/60
running SunOS 3.5.1 that has a separate partition on its SCSI
hard drive set aside as a file server for the MSDOS users
using PC-NFS version 3.0.

Whenever someone attempts to use a pipe in a DOS command line with
their default drive set to an NFS drive, the server's disk will
begin thrashing, and depending on the length of the data stream,
will tie up a large part of the network bandwith for a long period
of time.

Is this because PC-NFS is sending the stream over the network
with packets containing a single byte of data each?  If so,
can this behavior be modified?
