How do I disable the irqbalance service in Red Hat Enterprise Linux?

Solution Unverified - Updated -

Issue

Release Found: Red Hat Enterprise Linux, all versions

Solution

irqbalance is a service which increases system performance by reassigning various IRQ's to system CPU's depending on the workload involved. This is primarily relevant only on x86 or x86_64 systems.

To disable this service, do one of the following as root:

  • Use redhat-config-services (system-config-services on Red Hat Enterprise Linux 4) and uncheck the irqbalance service for all runlevels.

  • Execute the following commands:

     service irqbalance stop
 chkconfig --level 123456 irqbalance off

The service command will stop the irqbalance service immediately.  The chkconfig command will prevent it from starting on subsequent reboots. There is no need to reboot the system after making these changes. You might also want to review How do I enable CPU IRQ affinity?
