| 15 | ---help--- | |
| 16 | The Kyber I/O scheduler is a low-overhead scheduler suitable for | |
| 17 | multiqueue and other fast devices. Given target latencies for reads and | |
| 18 | synchronous writes, it will self-tune queue depths to achieve that | |
| 19 | goal. | |

| 24 | BFQ I/O scheduler for BLK-MQ. BFQ distributes the bandwidth of | |
| 25 | of the device among all processes according to their weights, | |
| 26 | regardless of the device parameters and with any workload. It | |
| 27 | also guarantees a low latency to interactive and soft | |
| 28 | real-time applications. Details in | |
