The Kyber I/O scheduler is a low-overhead scheduler suitable for
|
|
multiqueue and other fast devices. Given target latencies for reads and
|
|
synchronous writes, it will self-tune queue depths to achieve that
|
|
goal.

BFQ I/O scheduler for BLK-MQ. BFQ distributes the bandwidth of

regardless of the device parameters and with any workload. It
