      Description

      We recently added functionality to checkpoints, so that the amount of dirty data in cache is stepped down prior to the checkpoint starting. That helps most of the time, but introduces performance throttling in some workload/cache size configurations.

      Add a configuration option so applications can disable the step down if it isn't helping them.
