Applies to 2.6.28-rc6-00184-gd9d060a. Compare ext4's journalling with anything but ext3's. These use the same journalling modes, most other Linux filesystems do only metadata journalling.

So when comparing with a metadata-only journalling filesystem, such - as ext3, use `mount -o data=writeback'. And you might as well use + as jfs or xfs, use `mount -o data=writeback'. And you might as well use `mount -o nobh' too along with it. Making the journal larger than the mke2fs default often helps performance with metadata-intensive workloads. -- Hilsen Harald. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
