XFS is slower than ext4 on certain metadata-heavy workloads, and faster in multiple-stream workloads. It also scales better than ext4 on very big filesystems. It is, however, more memory-hungry. I use it extensively wherever I don't expect more than one crash an year. Otherwise, I go with ext4 (better fsck). > I'm preferring ext4 simply because it's more likely to be supported out > of the box in most scenarios and to keep my installations as simple as > possible as it's unlikely I would feel any real difference by switching > to another filesystem.

As far as I understand, xfs is an excelent filesystem and should probably be considered whenever filesystem performance can significantly impact your application. I'm preferring ext4 simply because it's more likely to be supported out of the box in most scenarios and to keep my installations as simple as possible as it's unlikely I would feel any real difference by switching to another filesystem.

Serious question - I know it has its advantages for particular scenarios, but I don't know how it stacks up in general-purpose use, and I've never run across an accounting of its disadvantages in a context which struck me as reliable. Beyond just xfs, I'd also be interested in the same sort of information (downsides - or more like really trade-offs - and suitability for general-purpose use) for other not-so-typical filesystems. I've never been entirely happy with just defaulting to extX for most filesystems every time I build a new machine, but the last time I did a build with something else it was reiserfs, and that wound up having problems in the long run - not to mention ending up relatively unsupported, AFAIK, given the fate of its namesake and primary developer. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
