How to lower the load average on a server with more than 50% in 10 seconds

$uptime
… load average: 0.54, 0.40, 0.36

$sudo vim /etc/fstab
(add the noatime option)

# /dev/sda3
UUID=8623d9e3... / ext3 defaults,errors=remount-ro,noatime 0 1

$sudo mount -a
…
$uptime
… load average: 0.24, 0.16, 0.17

So far this completely unscientific proof.

More info about the noatime option.

    not only on a server, did this on my laptop (using an external usb hd) and firefox (which used to stall sometimes for a few seconds) works much faster now.
