batch dispatch may hurt io merge performance which is important for elevator, so please provide test data on real HDD. & SSD., instead of null_blk only, and it can be perfect if merge sensitive workload is evaluated.
Ok, I'll provide test data on HDD and SSD that I have for now. For the elevator IO merge case, what I have in mind is that we issue small sequential IO one by one with multiple contexts, so that bios won't be merged in plug, and this will require IO issue > IO done, is this case enough? Thanks, Kuai
