I am currently benchmarking NVMe SSDs with Cassandra and am getting very bad 
performance when my workload exceeds the memory size. What mount settings for 
NVMe should be used? Right now the SSD is formatted as XFS using noop 
scheduler. Are there any additional mount options that should be used? Any 
specific kernel parameters that should set in order to make best use of the 
PCIe NVMe SSD? Your insight would be well appreciated.

Thank you,
Justin Sanciangco
