Of course if your app isn't producing TCP flows this won't help at all. ATR only works with TCP.

If you run the set_irq_affinity.sh script each queue will be affinitized to a CPU. Now any flows initiated from that CPU will be associated with that queue. Is this not what you're seeing?

I have a system with 32 cpus. On 31 of those cpus I have an app running (affined to that cpu). My ideal goal is to have 32 separate flows, each one hashed on some unique field such that I can route the interrupt for each flow to the cpu that will process that flow in userspace. As a fallback, I'd like 32 flows even if I can't ensure that they're routed to the same cpu that will ultimately handle the flow. From what I can tell the simple RSS mode only gives 16 queues, but when using virtualization I can get up to 64 pools. Can I use VMDq to get the extra pools/queues without actually starting up VMs? Can I assign multiple MAC addresses to the various pools/queues? How would I do this given the current driver?
