De este Wiki do Debian :
Low-Latency IO-Scheduler
(This step is not necessary for SSDs using the NVMe protocol instead of SATA, which bypass the traditional I/O scheduler and use the
blk-mq
module instead.)The default I/O scheduler queues data to minimize seeks on HDDs, which is not necessary for SSDs. Thus, use the
"deadline"
scheduler that just ensures bulk transactions won't slow down small transactions: Installsysfsutils
andecho "block/sdX/queue/scheduler = deadline" >> /etc/sysfs.conf
(adjust sdX to match your SSD) reboot or
echo deadline > /sys/block/sdX/queue/scheduler
Portanto, a resposta é: none
NÃO é um alias para noop
. none
significa "o agendador não é usado".
