This is what I'm seeing now: 1 null_blk device / 80 submit_queues / fio numjobs=80 9.4M IOPs 80 null_blk devices / 1 submit_queue per null_blk / fio numjobs=1 (1 per null_blk) 9.3M IOPs 1 null_blk device / 160 submit_queues / fio numjobs=160 9.8M IOPs 160 null_blk devices / 1 submit_queue per null_blk / fio numjobs=1 (1 per null_blk) 8.9M IOPs What is queued in mq-inflight looks to resolve the issue I've been seeing.
