I read from the documentation about how changing I/O Scheduler may significantly boost the performance of my cluster.
When I checked /sys/block/nvme0n1/queue/scheduler , it was set to along with other options mq-deadline and kyber.
Does anyone have any ideas what would be the most ideal io scheduler algorithm between two? or should I just leave it as ?
I'm running ES 6.6.2, running on Centos 7.6. My kernel version is 3.10.
