87 scheduler. If latency mode (called low_latency) is enabled, CFQ tries
90 latency (setting it to 0) ignores target latency, allowing each process in the
93 By default low latency mode is enabled.
98 latency mode is enabled. It will ensure that sync requests have an estimated
99 latency. But if sequential workload is higher(e.g. sequential read),
100 then to meet the latency constraints, throughput may decrease because of less
104 the read latency for some applications. This parameter allows for changing
106 throughput and read latency.
