[Bug 109830] CPU iowait higher when run the GPU multi decoding threads

--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
iowait is an indication of userspace badness, that userspace is sleeping for
the gpu. That it goes down is quite possibly a regression... But the only
numbers that matter here is GPU throughput; did the rare of decoding jobs
increase or decrease (jobs per second)? Did the energy consumption change?
