all: IO scheduling improvements, tuning
...
Dastically boost random write performance on RAID controllers with BBUs.
Writeback is only performed when there is no IO contention / starvation.
The old IO contention controller was suited to workstations.
Now server loads are well-controlled even when BBUs are present.
