XFS Developer Takes Shots At Btrfs, EXT4

Software

Chris Mason of Btrfs fame wasn't the only Linux file-system developer talking to the public last week. While the Btrfs talk was going on in Los Angeles at SCALE 10x, Dave Chinner was down under in Australia at LCA2012 talking about XFS. His talk included some controversial shots at EXT4 and Btrfs.

During his Linux.Conf.Au 2012 presentation in Barratt, Australia, Chinner first talked about the XFS meta-data problems of the file-system's meta-data modification performance being terrible. EXT4 can be 20~50x faster than XFS with certain workloads like unpacking a Linux kernel source tar-ball package. However, with one major algorithm change and various performance optimizations, the XFS performance is now scaling much better (Dave recommends the Linux 3.0 stable series or newer for the best XFS support).
