> ---++ Linux-only -- "noatime"

>

> On Linux, there is a [[https://dbpedia.org/resource/Fstab][fstab]] parameter for mounting disks called "[[https://opensource.com/article/20/6/linux-noatime][noatime]]" that is used to eliminate the need by the system to make writes to the file system for files which are simply being read. This improves the performance of file access which can be significant for databases hosted on file systems where many read operations are performed, especially in the case where HDD (rotating) disk drives are in use.

> Many modern Linux systems now use "[[https://opensource.com/article/20/6/linux-noatime][noatime]]" or its associate "[[https://blog.confirm.ch/mount-options-atime-vs-relatime/][relatime]]" by default or this option can be set by manually in the <code>/etc/fstab</code> file by adding it to the fourth field for specifying the mount options of a device, for example:

>

> <verbatim>

> /dev/sda1 /opt ext4 defaults,noatime 0 2

> </verbatim>

>

> A system reboot is require for fstab changes to take effect.
