Title: Journaling
Post by: csonni on March 02, 2003, 05:30:00 PM

Is anyone running 10.2.4 with Journaling enabled (such as with Cocktail utility)?  Are there any benefits to having Journaling enabled?  Slowdowns?  Any comments?

The benefit to filesystem journalling is that if your computer crashes while it's writing to your hard disk, the hard disk directory is less likely to become corrupted; Disk First Aid need only scan the journal, not the entire hard disk, to verify filesystem integrity.

The downside is that it slows down disk access. A LOT. By about 20%, in non-MacOS X Server configurations.

Generally speaking, filesystem journalling is only useful on server systems.
