Actually xfs's default (only) mode is more like writeback than ordered. So that's a fair comparison. I bet it is xfs's barriers that hurt it, though - while they are pretty much required on a single disk with a volatile write cache, I think xfs's barrier implementation hurts it more than barriers for ext* -Eric - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
