NFS Over SLIP or PPP

NFS Over SLIP or PPP

You can run NFS over a SLIP or PPP link. NFS will be very slow because of the amount of information transferred in NFS transactions. You may be able to improve performance with these measures:

Use NFS with modems faster than 9600 bps.
If your modem offers a choice between v.32 mode and "batch-oriented" or "half-duplex" mode (for example, PEP), use the batch-oriented mode.
Some dialers require v.32 or PEP mode. When choosing a new modem mode, verify that the dialer you specify uses the mode you want. Dialer modes are noted in the file /etc/uucp/Dialers.
Use one of the SLIP header prediction and compression options.
For more information regarding the SLIP compression options, comp and cslip, see the slip(1M) reference page.
Adjust the NFS options rsize, wsize, timeo, and retrans when mounting NFS file systems.
To improve performance, read and write smaller blocks and specify longer timeouts. See the fstab(4) reference page for more information on NFS filesystem options.
