For latency-sensitive applications, lower the value of this parameter and limit the command queue depth on the storage so that write-back I/O cannot fill the device queue with write requests. When the device queue fills, other processes attempting to perform I/O operations are put to sleep u...
一般queue_depth与nr_requests不在一个路径下面 nr_requests 是在 queue 目录下面 但是queue_depth 其实是在 device 目录下面. 也就是说 队列的数量 其实是 队列的属性 队列的深度, 更像是设备的属性. 设备支持的深度的情况. 很多linux 发行版默认的数值是 1014 cat /sys/block/sda/device/queue_depth 如果设...
…tmap The per-hctx nr_active value can no longer be used to fairly assign a share of tag depth per request queue for when using a shared sbitmap, as it does not consider that the tags are shared tags over all hctx's. For this case, record the nr_active_requests per request_queu...
