NAME

noage, nopff, noswap, on − run a command with priority aging, PFF, swapping, or processor migration disabled

SYNOPSIS

/usr/etc/noage command [ arguments ]

/usr/etc/nopff command [ arguments ]

/usr/etc/noswap command [ arguments ]

/etc/on proc command [ arguments ]

DESCRIPTION

Noage executes command (and its children) with priority aging disabled.  Ordinarily, process priority is an inverse function of the process’s CPU usage in the recent past.  (See proc_ctl(2)).

Nopff executes command without the command (or its children) being subjected to PFF adjustments.  PFF (Page Fault Frequency) adjustments are changes in the resident-set size based on the frequency of page faults.  (See vm_ctl(2)).

Noswap executes command with swapping for the command (and its children) disabled.  (See vm_ctl(2)).

On executes command on processor number proc, with processor migration disabled for the command (and its children). (See tmp_affinity(2)).

These commands may be nested; for example:

/usr/etc/nopff /usr/etc/noswap /etc/on 0 mycommand arg1 arg2

executes mycommand with swapping, PFF-ing, and processor migration disabled. 

These commands are effective only when invoked by the superuser, unless the underlying system call option has been configured for non-superuser processes.  See the proc_ctl(2) and vm_ctl(2) manual entries for configuration options.
