Hi Alex,
Well, every file system has its good points and its flaws. Reiser set out to
create the "perfect" file system, and ReiserFS performs admirably on lots of
small files - better than any of the others. Its main flaw is that version 3
is prone to FS corruption, and version 4 is not complete (you can run it, with
a kernel patch, but it is not everything that it was promised to be).
JFS, in my experience performs equally well with all sizes of files, with the
drawback that, with time, it will slow down (probably due to file system
fragmentation). I find that doing a full backup, running 'mkfs.jfs' on the
partition, and restoring the data fixes that problem.
XFS. I've used it and, believe it or not, I found it not really much faster
than the EXT3 file system. Then there is the problem that it uses extensive
buffering to achieve this "speed boost", which I never saw - basically meaning
that you must have a UPS or you *will* lose data.
EXT3. Of course we all know the benefits and flaws of this one, and its
predecessor. I thought I would bring it up because it is the 'tried and true'
file system of Linux based systems.
Regards,
Chris
