This is looking very nice. 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.
Thanks!!!
Brian
