BTW, why do you drive nvme via megaraid instead nvme driver?
And by the way, after Jan's patch "blk-mq: Improve performance of non-mq
IO schedulers with multiple HW queues", scsi_run_queue_async() can only
garantee to run hw queue for the current cpu, not all the hw queues.
That isn't true, each hctx is still run in case of none & kyber
scheduler.
And I really suspect that why Jan's patch can improve performance is
because it avoid many run queues from scsi_run_queue_async().
Yes, but current default hctx shared elevator is deadline.
thanks,
