[CentOS] ext3 filesystem performance question

It'll behave faster, but it will be slightly less careful with your
data. For example, commit=15 means that journaled data is commited to
the drive very 15 seconds instead of every 5. If you're okay with this
then it's not a big deal. Noatime is a performance tip usually good
for webservers or virtual machines, or any other place where you may
not care about recording file access times.

Changing 'data=foo' mount options are something that must be examined
and tested, much as changing the elevator options. There's some good
documentation in
/usr/share/doc/kernel-doc-2.6.9/Documentation/filesystems/ext3.txt
