Make sure you're using the --times option to reset the file times
after they're transferred. In fact, you may just want to use the
--archive option which wraps up this and others.

We did some performance tests the other day on a fairly slow machine.
On a 100Mbps network rsync achieves about 6.7MB/s. The absolute limit
is 12MB/s, contention and ethernet/ip/tcp overhead reduces it to about
8MB/s. So rsync is within shouting distance of full network
utilization. Make your own measurements, of course.
