Based on the behavior I see when using rsync, without
really knowing what's going on, it seems that the
sending side first does a lot of disk access,
then the receiving side does, and then
the sync begins over the network. It would
save a lot of wall-clock time if the sending
and receiving side could both be hitting
the disk at once. At least in my use case,
with whatever version of rsync I happen to be
using.
