Btrfs file system, Kubuntu 10.10

I'm using the Btrfs file system with Kubuntu 10.10 x64. It seems fast, I like it but installing programs seems slower....not sure it's the file system, but I'd like some seat of the pants observations from others using this.

 

Phoronix thinks Btrfs is slower than ext4 on kernel 2.6.35.

BTRFS is experimental frankly speaking for home users I don't see the need to switch to it if it offers neither stability nor performance improvements.
The advance features for BTRFS is useful for server backups but the irony is you don't use beta filesystems for storing your precious data.

 

It's fast on this precision m6500, but yeah, I'm testing it....thanks for the link I'm going to read that.

EDIT: Actually, I'm using it with Ubuntu 10.10 x64 rather than Kubuntu.

 

It was hyped to offer both of those and really isn't intended for home users, to wit:.

Btrfs (B-tree file system, pronounced "Butter F S", "B-tree F S"[2]) is a GPL-licensed copy-on-write file system for Linux.
Btrfs is intended to address the lack of pooling, snapshots, checksums and integral multi-device spanning in Linux file systems, these features being crucial as the use of Linux scales upward into larger storage configurations common in the enterprise.[1] Chris Mason, the principal author of the filesystem, has stated its goal was "to let Linux scale for the storage that will be available. Scaling is not just about addressing the storage but also means being able to administer and to manage it with a clean interface that lets people see what's being used and makes it more reliable."[3]
Oracle has also begun work on CRFS (Coherent Remote File System), a network filesystem protocol intended to leverage the Btrfs architecture to gain higher performance than existing protocols (such as NFS and CIFS) and to expose Btrfs features such as snapshots to remote clients.[4]
Btrfs 1.0 (with finalized on-disk format) was originally slated for a late 2008 release,[5] but a stable release has not been made as of October 2010. It has, however, been accepted into the mainline kernel for testing as of 2.6.29-rc1.[6] Several Linux distributions have also begun offering Btrfs as an experimental choice of root file system during installation, including Ubuntu 10.10, SLES 11 SP1, Red Hat Enterprise Linux 6,[7] and MeeGo.[8]
The principal developer of the ext3 and ext4 file systems, Theodore Ts'o, has stated that ext4 is a stop-gap and that Btrfs is the way forward,[9] having "a number of the same design ideas that reiser3/4 had".[10]
