WARNINGS

The intctl command can be executed only by the super user. The

intctl command should be used

only by performance analysts for performance tuning purposes. If care is not taken to redistribute the

interrupts properly, it could lead to a decrease in the overall system performance by overloading some

processors and by not optimally utilizing the remaining processors.
