What is Irqbalance
Irqbalance is a daemon to help balance the cpu load generated by interrupts across all of a systems cpus. Irqbalance identifies the highest volume interrupt sources, and isolates each of them to a single unique cpu, so that load is spread as much as possible over an entire processor set, while minimizing cache miss rates for irq handlers.
Building and Installing

Irqbalance is currently hosted on github, and so developers are welcome to use the issue/pull request/etc infrastructure found there.
When something goes wrong, feel free to send us bugreport by one of the ways described above. Your report should include:
- Irqbalance version you've been using (or commit hash)
- content of smp_affinity files - can be obtained by e.g.:
$ for i in $(seq 0 300); do grep . /proc/irq/$i/smp_affinity /dev/null 2>/dev/null; done
- your hw hierarchy - e.g.
