Reduce File System Housekeeping

UNIX file system (UFS) volumes maintain the time that each file was accessed. Note that the following change does not turn off the access time updates when the file is modified, but only when the file is accessed. If the file access time updates are not important in your environment, you can turn them off by adding the noatime parameter to the data volume's mount point in /etc/vfstab. For example:

/dev/dsk/c0t5d0s6 /dev/rdsk/c0t5d0s6 /data0 ufs 1 yes noatime
