Optimize for single disk and storage array performance

The common “noatime” and “nodiratime” settings eliminate the need for writes during reads to help performance and disk wear.  The “barrier” and “writeback” settings are a little less common and may not be what you’d normally set. Although those settings present a very slight risk for loss of data on disk failure.

noatime
bodiratime
barrier=0
data=writeback
ulimit -n 65536

vi /etc/fstab
