I/O scheduler for ES 7.0

We are using ES 7.5.0 As per the documentation, selecting the correct i/o scheduler should optimize the ES performance. In our system when I checked in /sys/block/sdb/queue/scheduler, I could see 3 scheduler options

  1. noop
  2. deadline
  3. cfq

We are using azure blockstorage in our system. So which scheduler should be best for our configuration?

We used to recommend noop, but I don't know if that's still relevant. Hopefully someone else with more knowledge can comment :slight_smile:
