# irqbalance is a daemon process that distributes interrupts across

# CPUS on SMP systems. The default is to rebalance once every 10
|
|
# seconds. This is the environment file that is specified to systemd via the
|
|
# EnvironmentFile key in the service unit file (or via whatever method the init
|
|
# system you're using has.
