The latter I can > confirm --- you can see the performance degradation quite easily on a single > disk, so the mention of LVM in the summary is probably misleading. Just a note, performance degradation is not that huge for XFS, as soon as i understand this is because it batch several inode writes in to one 'log' so less barriers required But nor than less this is generic writeback issue. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
