-#
-# The default I/O scheduler for single-queued block layer devices offers
-# satisfactory performance for wide range of I/O task, however choosing an
-# alternative scheduler may potentially yield better latency characteristics
-# and throughput.
-# "noop" is an alternative scheduler, in comparison to other schedulers it
-# may offer more consistent performance, lower computation overhead, and
-# potentially higher throughput.
-# For most SAP environments (RAID, storage arrays, virtualizaton) 'noop' is
-# the better choice.
-# With the new introduced multi-queue scheduler for block layer devices the
-# recommended I/O scheduler is 'none' as an equivalent to 'noop' for
-# single-queued block layer devices.
-#
-# So IO_SCHEDULER can now contain a comma separated list of possible
-# schedulers, which are checked from left to right. The first one which is
-# available in /sys/block/<device>/queue/scheduler will be used as new
-# scheduler setting for the respective block device.
-#
-# When set, all block devices on the system will be switched to one of the
-# chosen schedulers.
