I was looking in google for information on file system comparison on Linux, and the best reading that I found is http://bulmalug.net/body.phtml?nIdNoticia=1154. However they compare them with file coping and creation and kernel compilation, which is not very related to how Oracle DB works. So my question is what is your experience? In your opinion, which is the best file system and why? Is there a difference between Ext3, XFS, JFS, ReiserFS? Is there meaning to use non-journal file system like Ext2?

Thanks in advance for all opinions
