irqbalance

distributes hardware interrupts across CPUs

TLDR

Start irqbalance

$ sudo irqbalance

Run in foreground

$ sudo irqbalance --foreground

One-shot balance

$ sudo irqbalance --oneshot

Debug mode

$ sudo irqbalance --debug

Ban specific IRQ

$ sudo irqbalance --banirq=[irq_num]

irqbalance distributes hardware interrupts across CPUs. It optimizes interrupt handling for multi-processor systems.The daemon monitors IRQ patterns and migrates them for better load distribution. It improves performance on multi-core systems.

PARAMETERS

Run in foreground.

--oneshot

Balance once and exit.

--debug

Enable debug output.

--banirq IRQ

Exclude IRQ from balancing.

--policyscript SCRIPT

Custom placement policy.

--pid FILE

INSTALL

sudo apt install irqbalance

sudo dnf install irqbalance

sudo pacman -S irqbalance

sudo apk add irqbalance

sudo zypper install irqbalance

nix profile install nixpkgs#irqbalance

CAVEATS

Runs as daemon. May conflict with manual IRQ affinity. Linux-specific.
