Running ZFS Natively On Linux Slower Than Btrfs
An anonymous reader writes "It's been known that ZFS is coming to Linux in the form of a native kernel module done by the Lawrence Livermore National Laboratory and KQ Infotech. The ZFS module is still in closed testing on KQ infotech's side (but LLNL's ZFS code is publicly available), and now Phoronix has tried out the ZFS file-system on Linux and carried out some tests. ZFS on Linux via this native module is much faster than using ZFS-FUSE, but the Solaris file-system in most areas is not nearly as fast as EXT4, Btrfs, or XFS."
Who would have thought that a first-release Beta kernel module would not run as fast or be as reliable as the stable implementation for other operating systems, or the stables on Linux?
Thirty four characters live here.
ext2 is faster than ext3, simply because it does less. ZFS has many, many features most other FS don't have but they do come at a price.
I can write the fastest file system around, assuming you don't put much weight on the whole 'being able to read the data back' thingie.

Snapshots.
And I don't just mean any snapshots.
Done right, like in ZFS, they are fast.
Faster than BSD's UFS snapshots, faster than using LVM's fs-agnostic snapshots. For people who need them, they're great.
