Hi Stefan, there are still users with large HDD installations and I think this will not change anytime soon. What is the impact of encryption with the new settings for HDD? Is it as bad as their continued omission from any statement suggests?
We only tested flash, as we don't have any spinners to test on. So not sure what the impact would be. From the blog post I got that the queuing was there to mainly help workloads with spinning disks. But all that was valid in 2015. It specifically mentions benefit for CFQ scheduler, that since has been removed from the linux kernel.
So, it would be interesting to know if it is still needed on spinners when used with Ceph ...
