It appears that the overall transfer rate has decreased a tiny bit. But, the
big advantage of not doing "sync" on mount, is that the system can queue the
writes. So, for anything that fits into kernel queues, the writes appear way
faster to the user. That's my understanding of the difference between sync and
not using sync.
