Turn off the CentOS write disk feature

A Linux file has a default of 3 time.
Atime: The access time for this file.

CTime: The time when the inode for this file has changed.

Mtime: The modified time of this file.

If you have multiple small files (such as multiple small images on a Web server page), there is usually no need to log the file's access time, which reduces the I/O to the write disk. How do you configure this?
First, modify the file system's configuration file: Vim/etc/fstab. Then, use both the Noatime and Nodiratime commands in a partition that contains a large number of small files.
For example:/dev/sda5/data/pics ext3 noatime,nodiratime 0 0 so the file is accessed and no more I/O is generated for the write disk.
