INTRBALD_INTERVAL

The daemon checks if the system requires any interrupt balancing after this

interval. The interval is speciﬁed in seconds; the valid range is 5 seconds to

INT_MAX seconds (see limits (5)). The default is 60 seconds.

Setting this value too small could cause unnecessary interrupt migrations.

RETURN VALUE

Exit values are:

0 Successful completion.

>0 An error condition occurred.

WARNINGS

The

intrbald command can be executed only by the superuser. This command should be used only by

performance analysts for performance tuning purposes. If the interrupts are not redistributed properly, a

possible decrease in overall system performance can occur. Some processors can become overloaded while

other processors will not be optimally utilized.
