What's the minimum link speed you need to reasonably run NFS over?
We're thinking about using it between two machines connected by a 128 kbps
serial line. Is that fast enough to have a reasonable chance of it working
well?

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). ---------------------------------------------------------------------------- /////// // // Peter Hausken, University of Oslo // // // // PB. 1059, Blindern, N-0316 OSLO 3, Norway /////// ////// Voice: +47-2-453524 Fax: +47-2-455770 // // // Internet: Peter.Hausken@USE.UiO.NO (peterh@ifi.uio.no) // // // X.400 SA: G=Peter;S=Hausken;OU=USE;O=UiO;P=UNINETT;C=NO
