We can increase ext3 performance, hence increasing Hard Disk performance by ~40%, and decrease power consumption by Hard Disk, if we provide “noatime,nodiratime” options during partition mounting. Actually what happens is: whenever a file/directory is accessed, its atime “access time” is updated with epoch. These two options prevent these not-so-useful disk accesses. Hence
performance improvement.
The sample mount point (/home) entry in /etc/fstab may look like:
$ cat /etc/fstab | grep home /dev/sda2 /home ext3 defaults,noatime,nodiratime 0 0

hi mitesh,
nice article. just a clarification, by tuning the parameters of the ext3 protocol, shouldn’t we calling it us, file system performance optimization. if i’m not hard disk has its own threshold and performance predefined by the factory already.
for ex rpm.
Hi,
Sorry, my mistake in not using appropriate title.
Yes harddisk has its own tweaking parameters, some are factory set and
some can be set by “hdparm” command.
