Is your system slow? Do you have to wait 6.2 seconds to start Firefox and other heavy applications?

Well, what you need is the “noatime” filesystem mount option! What exactly happens when system files are read? They are written too! The system writes access times to the files causing unnecessary IO traffic between you and your HDD.

To avoid this, you can mount all your partitions with the noatime option. Simply append “,noatime” beside the “defaults” option in the /etc/fstab and your done!

  /dev/sdb2          /          ext3          defaults,noatime          0  1

Make sure there is no space between defaults and noatime, only a comma.

To test this instantly, execute:

mount -o remount /dev/sdb2

Have fun with the new Performance!
