Benchmarks The choice of filesystems on Linux is vast, but most people will stick with their respective distributions' default choices, which will most likely be ext3, but you're free to use ReiserFS, XFS, or something else completely if you so desire. Things are about to change though, with btrfs just around the corner. To bridge the gap between now and btfrs, ext3 has been updated to ext4, which adds some interesting features like extents, which are already in use in most other popular file systems. Phoronix decided it was time to do some performance checking on ext4.

Encryption performance

I'd be really curious to see how the performance of whole disk encryption is affected by filesystem choice. I have a 1.5 TB RAID5 (4x500GB SATA2) entirely encrypted using dm-crypt and dm-raid with XFS on the RAID. I used to have the entire system system encrypted but the performance hit was too painful. It would be interesting to see if the filesystem choice would have much impact on that.
