I'm not saying that you should always use a software queue. The queue is only needed when your hardware queue is full. You can make it zero-length for requests that are not MAY_BACKLOG, i.e., only MAY_BACKLOG requests need to be queued, everything else can just be dropped when the hw queue is full. If you do that I don't see why the performance should be any different.
