In the first instance you should set a suitable scheduler for your drive(s). I understand with SSD the 'Deadline' is appropriate, but at least for spinning drives you should give BFQ a try. You can red about BFQ here: Documentation/block/bfq-iosched.rst If you prefer, you can even switch the IO scheduler in real time while monitoring performance, to verify which IO scheduler works best for your use case: Documentation/block/switching-sched.rst
