JFS has a problem in that it must be periodically defragged. Reiserfs is also fast and seems to work acceptably (finally). ext3 is the big loser--2/3 the speed of ext2 unless you run it in non-journaling mode, which is kinda pointless.
NO journaling filesystem will help you with file security or data integrity; it will only help you recover it faster if it is recoverable (these days it usually is) The remarks on speed are from my own test routines on my own systems, timing the creation and deletion of 100,000 files in each filesystem and the updating that changed the sizes of those files randomly for a total of 50,000 updates which either doubled or halved file size. and finally copying files amountiong to 500Mb in chunks of 1Mb, 50 Mb and 167Mb... filecopy was weighted 5/9 while creation, deletion, 1/9 each and update 2/9. to arrive at the relative ratings, and really the three (JFS, XFS, and Reiser) were in their own group somewhat ahead of ext2 while ext3 was behind ext2 in speed. I was not perverse enough to try FAT32 for comparison, cause we have enough FUD and unprofessional comparisons around, and FAT32 is an extension of a filesystem that was originally designed for floppy.
