There is a ton of information about JFS and XFS on the net. All you
need to do is check the Wikipedia filesystem comparison page or Google
search for filesystem comparisons. The short of it is:

ext3 - good general purpose FS (not the best performance, but stable)
xfs - excellent performance with huge files and huge filesystems
jfs - similar to XFS but I think it has better performance when under
heavy I/O load
Could you define 'huge files' and 'huge filesystems'? Can you give me some numbers?


At work we deal with files of size 1 GB to 100 GB on a regular basis. I
would classify those as large.

I see. I was asking since I have a whole drive full of videos and such which are
usually between 100MB and 300MB per file. So I guess XFS would not really be the
best choice for them. I got ext3 everywhere at the moment and wondered if I
could get a bit more performance by using another filesystem. And since I only
used ext3 up until now, I don’t really know which other filesystem to trust.

XFS supports files up to a size of 8
exabytes and filesystems also of size 8 exabytes. I am not sure of the
limitations on JFS.

OK, that seems only important for enterprise levels. I don’t think that I will
reach these sizes at the moment.


Regards, Mathias
