Mounting as a temporary filesystem

To improve performance, your temporary filesystem (for example /tmp, /u/tmp, or /usr/tmp), can be set up as either an EAFS, AFS, S51K or HTFS filesystem type. If you have any temporary filesystems, you can select this option so they are mounted as temporary filesystems automatically every time the system is rebooted.

Temporary filesystems are updated less frequently and are recommended for use on filesystems containing temporary data only. If this option is used on /tmp, the overall system performance may improve.
