6 low-latency capabilities. In addition to cgroups support (blkio or io
7 controllers), BFQ's main features are:
9 - BFQ guarantees a high system and application responsiveness, and a
10 low latency for time-sensitive applications, such as audio or video
12 - BFQ distributes bandwidth, and not just time, among processes or
18 schedules that may lead to a lower throughput. If your main or only
19 goal, for a given device, is to achieve the maximum-possible
20 throughput at all times, then do switch off all low-latency heuristics
