+ While there is much room for improvement in update speed, one factor + is whether or not all writes are automatically forced to disk. By + default, "autoSync" is enabled, which keeps the database file in a + more consistent state, but can be very slow for large updates. + Disabling "autoSync" can dramatically increase update speed, but + exceptions during update can leave the file in an unusable state. + So, modifying this option essentially trades off speed for + recoverability. +
