So what you say is you saw a consomed == 1 [1] most of the time?
[1] from

Exactly. By processing 1 completion per interrupt it makes perfect sense
why this performs poorly, it's not worth paying the soft-irq schedule
for only a single completion.
What I'm curious is how consistent is this with different devices (wish
I had some...)
