noatime

If you need I/O performance bust it might worth to turn on noatime flag on important partitions. Look down to see how it pushed down the read level on a server with Apache serving a static content.


Usually I add noatime flag during a system installation, but this time forgot about it and had to remount the file system. Thanks that mistake I got this beautiful image ;)
You can go even further and turn on nodiratime, it should decrease read even more.
