In going down the NUMA rabbit hole, I discovered "irqbalance".��

8 Does anyone have an opinion on its usefulness? It is in portage.

On some multicore arm systems I am using irq affiity to steer

11 certain irq's to faster CPU's (network, usb) - but from what I
12 have been reading, irqbalance can improve a mixed workload but a
13 system with a small number of busy irq's is better served by
14 separating and locking them to different, more powerful
15 processors. e.g., arm big.LITTLE architectures.
