[LUNI] file system limitations

[Erik Lickerman]

Yeah- one of the other posters pointed me to ReiserFS as well.  It looks
ideal for my application.  As a person raised on Mac and Windows it is
amazing that one can choose his filesystem independently from his operating
system.  I wonder how the Windows server OSs  can compete on performance,
when the UNIX OSs can swap out filesystems?

Right.  Also, not all filesystems have that linear search issue.
Reiserfs comes immediately to mind, perhaps because it has long used
the subtitle "trees are fast!"  :-)  I'm not very familar with other
non-ext2/3 filesystems, but I wouldn't be at all surprised if XFS
handled this well, too.  And isn't there a change along these lines
coming to the ext2/3 line too?
