We already have irqbalance turned off (uninstalled, actually), and we're using the same number of queues on each device (we get the number of queues by taking the number of cores divided by number of interfaces). I am wondering if not having the matching queues for the ingress interface and egress interface on the same cores might be a contributing factor? --Zvi
