Subjectirqbalance beneficial these days?
It seems like the environment for which irqbalance was originally
designed to optimise was high-interrupt-rate workloads [1].

But, with NAPI, multiple queues, threaded/split handlers, TCP offload,
interrupt moderation, RDMA etc, does anyone know it to be beneficial
in servers over the default kernel MSI vector setup? I can see it only
being beneficial in certain specific circumstances (eg metro VoIP
router) and perhaps that's application dependent at that.
