Thomas Schoebel-Theuer	c319230fa1	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.	2013-01-23 20:06:49 +01:00
