Oracle on ext4 warning
I bought a new laptop recently ( Dell Studio XPS 16 ) Core 7i, 8Gb, 7200RPM disk. I installed my Linux distro of choice, Fedora 12, and started installing Oracle. Yeah I know Fedora isn’t a supported OS, but I’ve got almost ever version from 8.1.7.4 to 11.2 and I’ve never really hit any problems for testing use.
To justify my new purchase, I thought I check how lighting fast it was in comparison to my 3+ year old Dell D620. I timed how long it would take to create a 10.2.0.4 database – problem was ….
Old Laptop : ~10 mins
New Laptop : ~20 mins
The only difference I could see was that the old machine was 32bit the new one was 64bit and wasted a bit of time going down that dead end. Anyway after lots of investigation I eventually noticed that the old machine the database filesystem was built with ext3 ( it was created back when Fedora 6 was current), the new laptop was using ext4.
I found a blog Mount options to improve ext4 file system performance and tried the options suggested – and magically the database creation time dropped from 20mins to ~6mins ! Then to confirm I rebuilt the filesystem as ext3, and retained the 6min build time.
ext4 has been standard on the bleeding edge distros for a while now, and is starting to appear in the enterprise Linux distos, Red Hat EL6 beta lists as a feature. So watch your Oracle performance if you are considering ext4.

I guess I’m not seeing the warning. You say ext4 and ext3 both did the install in 6 minutes. Presumably you meant on the new laptop and aren’t saying what the old laptop had for FS (ext2? ReiserFS? something else?)
So it appears your issue was NOT ext4 but rather the new laptop and/or the difference between 32 bit and 64 bit. Can you explain why you think your issue was ext4? I’m apparently missing it in what you wrote.
