79 multiple queues in the group at the same time and achieve higher throughput
88 to recompute the slice time for each process based on the target_latency set
91 system to get a full time slice.
97 This parameter is used to calculate the time slice for a process if cfq's
101 time for each process to issue I/O request before the cfq queue is switched.
118 device request queue in queue's slice time. The maximum number of request that
125 executed for a certain amount of time(time_slice) before switching to another
126 queue. This parameter is used to calculate the time slice of synchronous
137 queue's time slice, a request will not be dispatched if the number of request
187 time will be distributed like the following.
206 Basic CFQ design is to provide priority based time slices. Higher priority
207 process gets bigger time slice and lower priority process gets smaller time
208 slice. Measuring time becomes harder if storage is fast and supports NCQ and
210 request queue at a time. In such scenario, it is not possible to measure time
214 single queue and also allow dispatch from multiple cfq queue at the same time.
255 flight at a time), then it cuts down on idling of individual queues and
286 time we do not idle on individual threads.
