Recent high-performance storage devices have exposed software inefficiencies in existing storage stacks, leading to a new breed of I/O stacks. The newest storage API of the Linux kernel is io_uring. We perform one of the first in-depth studies of io_uring,

Changing an I/O scheduler is performed on a per block device basis. For example, for non-multi queue device /dev/sda one can see the current I/O schedulers available using the following: 更改I/O调度程序是在每个块设备的基础上执行的。I/O调度器试图平衡对高吞吐量的需求，同时试图在进程之间公平地共享I/O请求。
