However, if you want to get fairness in a case like this, a new bandwidth control policy which controls accurately according to assigned weights can be added to dm-ioband.
Are you saying that dm-ioband is purposely unfair, until a certain load level is reached?
We regarded reducing throughput loss rather than reducing duration as the design of dm-ioband. Of course, it is possible to make a new policy which reduces duration.
... while also reducing overall system throughput by design? Why are you even bothering to submit this to the linux-kernel mailing list, when there is a codebase available that has no throughput or fairness regressions?
