With the EXT4 file-system having been stabilized with the Linux 2.6.28 kernel, the Ubuntu developers are preparing to adopt this evolutionary Linux file-system update. EXT4 will not replace EXT3 as the default file-system until at least Ubuntu 9.10, but as of yesterday, Ubuntu 9.04 now has install-time support for EXT4. In this article we are looking at the EXT4 support within Ubuntu as well as providing a few Linux file-system benchmarks from a netbook-embedded solid-state drive. In this article we have published Ubuntu benchmarks of EXT4, EXT3, XFS, JFS, and ReiserFS file-systems.
Please conduct a test with the latest version of btrfs.
I thought BetterFS wasn't even fully implemented yet, or can it do most all the basics already? Regardless, I'm sure it won't be nearly as fast as later on when everything gets stabilized more, but benchmarks of it would indeed be interesting.
And don't forget Tux3! ^^
As far as EXT4 is concerned, it looks great, thanks for the benchmarks!
