ext4 – how to improve performance
My workstation Linux distro of choice is Ubuntu, right now at version 10.04. Despite the fact that ext4 is default file system in this release, I thought I would stick with ext3 for awhile, but now I think I’ll use ext4 on my next Ubuntu box.
I had never done any real measurement where I would compare for example Oracle XE performance on ext2 vs. ext3 vs. ext4, nor did I experiment with other Linux file systems. I don’t care much about ext4 new feature as much as I do expect from file system on my Ubuntu workstation to perform decently while experimenting with different software (not necessarily Oracle all the time!). On several occasions I got a feeling that sometimes ext4 (ext3) just didn’t perform well but I did not bother to do any research of possible mount option optimization for ext4/ext3.
That’s why I found Nick Gauthier blog, Mount options to improve ext4 file system very interesting, definitely worth a bookmark in the form of this note. And mount options that Nick explained are also valid for ext3!
