NOAGE(8)

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.
