Background

IBM's Journaled File System, or JFS for short, is an outgrowth of its AIX operating system. JFS, Ext3, XFS and ReiserFS, are the big 4 of journaled file systems, and each has its own characteristics that make it suitable for different users. JFS is very fast, light, and efficient. Nevertheless it performs extremely well under a wide variety of situations, and draws lightly on the CPU on comparison to the others. See the links at the end of this article for benchmarking articles.
