Kernel Tuning (for SCO UNIX):
The following represents values that are different from the SCO-supplied defaults.
These are primarily for SCO 3.2.4 sites (for SCO Open Server 5.x sites, most of parameters below are automatically set for you; the NFILE, NOFILES and SHMMAX parameters are the only ones usually requiring adjustment).
Note: you can check your current values by printing the file /etc/conf/cf.d/mtune.
