Disabling "atime" option - Narender Rao - 06-05-2020

Hello all !How to turnoff the atime option in LL 4.8?? Recently I came to know that atime can be a cause of slowing down the performance of system with low resources and less ram! Please guide me regarding this small doubt and the way to implement if it is possible. 8)

Actually, it's part true. You can disable atime by editing the /etc/fstab as root and adding this line to each entry
Code:
noatime
, you may google how to do that to have a better idea, once you've finished adding "noatime", save and close the file, then reboot. Make a backup of the file before doing anything. However, like I said it's part true since you won't really notice any difference. This might've been useful in the past but  most recent/modern distros like Linux Lite do a good job handling I/O calls/performance operations by using "relatime" which is basically what disabling "atime" does. Also, this is mostly inteded for servers not desktops. So, I'd advice not to but instead look for other ways to achieve what you want; increase RAM if possible, add a SSD if possible. Upgrading your hardware if possible is the best way to assure you'll get the best out of your system. Here's a nice reading on using noatime you might want to check https://opensource.com/article/20/6/linux-noatime

Hope this helps! Smile
