It's odd that you're leaning towards JFS, when XFS is superior or nearly equal in almost every performance test, is more tunable, and has better and more extensive user space utils. In addition, XFS enjoys active, heavy development. JFS hasn't had a commit since January, only 2 commits this year and both in user space tools. XFS has had hundreds, most to kernel space. JFS is all but dead from a development and maintenance standpoint. XFS is alive and well, with constant bug fix work, efficiency streamlining of the code base, and feature development. http://oss.sgi.com/projects/xfs/ http://xfs.org/index.php/XFS_Status_Updates http://jfs.sourceforge.net/ http://sourceforge.net/mailarchive/forum.php?forum_name=jfs-commit&max_rows=25&style=ultimate&viewmonth=201001 Some performance comparisons in kernel 2.6.34-rc3: http://btrfs.boxacle.net/repository/raid/2010-04-14_2004/2.6.34-rc3/2.6.34-rc3.html Visit the above test results page often. The "fast" EXT4 data set was generated with a "cheat" optimization. A test run has not yet been made using a similar "cheat". When published it should show substantial gains over the EXT4 "cheat" optimization. Specifically addressing your 32K EXT3 limitation, XFS uses dynamic inode allocation. Because of this you won't run into a directory or file limit unless there are physically no more free disk sectors in the filesystem, i.e. the disk or RAID is completely full. With XFS, as long as you have free space on the disk you can write new files and directories. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
