We're running NFS between UNIX hosts and from PC's with PC-NFS to
UNIX-hosts across 64Kbps lines (Bridged Ethernet). It's just about as
slow as the line speed indicates. University of Oslo got a number of
institutes spread around the city and they are all connected to the
main campus using 64Kbps lines and their PC's got access to a local
UNIX-server and a remote sentral UNIX-server for common programs and
data.It's OK for starting small programs or saving small files, but I
wouldn't use as my primary disk. I've also tried running PC-NFS across
WAN's (64Kbps lines) on both cisco-cisco and X.25 networks. It works,
and is more easier than using FTP, but not much faster.

We had to limit the NFS write-size from the default 8Kb to about 1Kb
to make the remote drive writeable (Thanks to Geoff Arnold for the
PC-NFS patch).
