Default value for this parameter is 8ms.
latency
-------
This parameter is used to enable/disable the latency mode of the CFQ
scheduler. If latency mode (called low_latency) is enabled, CFQ tries
to recompute the slice time for each process based on the target_latency set
for the system. This favors fairness over throughput. Disabling low
latency (setting it to 0) ignores target latency, allowing each process in the
system to get a full time slice.
