I'm limited by the target machine in terms of IOPs, but the host shows
~10% cpu usage decrease, and latency improves slightly as well
which is more apparent depending on which cpu I'm running my IO
thread (due to the mismatch in comp_vectors and queue mappings
some queues have irq vectors mapped to a core on a different numa
node.
