If it doesn't take up too much CPU and space like they say..... WHY NOT!???

:p

I could go either way at this point. I/We haven't heard from Apple yet exactly how it will work, how it can be implemented, and what or if or when there will be a slow down in the system.

I'll definitely play around with it to see how well it works, but I don't think I'd permanently use it on my desktops.

Maybe my server, when I get one. :)

The question for me is do I need the Journaling system?
Sorry, but I don't even understand what it is exactly.

File Journaling is a way to ensure data integrity. If the system is shut down unclean, then possiblity of file corruption isn't as significant.

As for running it. It definitely makes the XServer more appealing. We are planning on putting a XServer in at a client for web hosting, and possibly 4d Server hosting (Database App). Journaling would be cool for the 4d server and may put the XServer ahead in running versus a Windows Machine.

The few things I've read on the subject say THERE IS a performance hit, in both CPU activities and disk space. Besides... I don't use my systems in an office environment, so why should I need it?

Well of course there is. Does anyone really think that you can right to the disc without the CPU processing the data to write?

well...i answered no...but i went ahead and turned it on to test it out in my build...6F15

im hoping...just maybe...it might kick jag in the rear when it comes to the endless application bounce...

i know they have basically nothing to do with each other, but i've seen wierder.

A reliable source has informed me that file journaling will be grayed-out in 10.2.2 and first offered as an option in 10.2.3.

from what i understand, its not going to be a GUI option at all. forget greyed out. this is gonna be an option for the technically inclined that would be the only people with any reason to have a journaling filesystem. it is now, and is supposed to stay, a command line option when it comes to OS X as a client.

Well, I don't use it on Linux (ext3), and don't see any reason to use it on OS X.

Journalling is a great safety device for critical servers. It costs a lot (in the disk IO system, which in all desktop computers and especially notebooks is already severely overtaxed and often the chief performance bottleneck). Anyone who characterizes journalling a filesystem as free for the user is either completely misunderstanding what they are talking about or has taken a sever blow to the head and is hallucinating.

High-end DB's already do journalling for you (Oracle, etc); I'm somewhat surprised that 4D doesn't (lowers my impression of 4D even more ...). Where the JFS adds value is in non-DB logging and storage, which is most often done direct to the file system.

Will JFS make your system more stable? I severely doubt it. Will it allow you to recover from a disk failure? Not likely. Will it help you if you are saving your Word document over the top of the old version and suddenly the power goes off? Yup. But a good backup plan would provide more benefits in other situations and most of the benefit in this unlikely scenario as well.

In general, the case for journalling is one for server admins, not for desktop users.
