How to add 'noatime' to fstab?

By adding the noatime option to your main partition within your fstab can significantly increase your IO and overall server/drive performance. Please be sure to have your data backed up. This shouldn't cause any data loss, but better be safe than sorry.

Code:

1. Open up /etc/fstab in your favorite browser.
2. Add the noatime option to the line you you want. 
Example: 
 /dev/sda7          /chroot          ext2          defaults,noatime          1  2
3. Save the file and close.
4. You now must remount that partition. No reboot necessary. Just run this command:
mount -oremount /chroot (replace chroot with the partition you added noatime to)

That's it!
