During the initial load, some speed up can be achieved by switching journaling off, by setting the {{journaling}} configuration parameter to {{false}}. All this does is to stop the transaction log being written to disk (in case of failure), but a noticeable speed up is possible. During normal use, it is recommended to enable journaling for more reliable recovery after an unexpected termination.
