"Recently, Linux has been undergoing something of a revolution with a respect to file systems. There are a number of projects including ext4 (See ext4 File System: Introduction and Benchmarks), squashfs, nilfs which have made it into the kernel, and tux3, which hasn't made it into the kernel yet but is under heavy development.

"And perhaps most importantly, btrfs. Btrfs holds the promise of giving Linux many enterprise class file system features similar to ZFS (See Solving Common Administration Problems with ZFS and ZFS on FUSE) but with even more features and better performance. In fact, many Linux experts think that btrfs is one of the keys to the future of Linux. While btrfs is not quite ready to be your only file system, it is in the kernel ready for testing and is still undergoing very heavy development.

"In this article we will introduce the key features of btrfs find out how it compares to existing file systems. We will also test it using iozone, with the understanding that it's still in development so performance will likely change over time."
