Increase Drive Performance by 40% using noatime<\/h2>\n

Are you feeling the heat on your dedicated server, getting high I\/O wait times?<\/p>\n

If you are using EXT3 partitions then it is worth checking to see if they are mounted using ‘noatime’. If they are not, then every read to your partition is also a write which can massively reduce hard drive performance.<\/p>\n

First, find all partitions mounted as EXT3 mount without noatime:<\/p>\n

# mount | grep ext3<\/pre>\n
\/dev\/sda1 on \/ type ext3 (rw,noatime)\r\n\/dev\/sdb1 on \/backup<\/strong> type ext3 (rw)<\/pre>\n
Any not showing the noatime<\/strong> attribute, simply remount like so:<\/p>\n
# mount -o remount,noatime \/backup<\/strong><\/pre>\n
You can do this without a server reboot, you can do this with the server live and with the partitions already mounted.<\/p>\n","protected":false},"excerpt":{"rendered":"
