One way I've been trying to speedup rsync may
not apply in every situation. In my situation
when files change, they usually change completely.
This is especially true for large files. So,
the rsync algorithm does me no good. So,
I've been using the "W" flag (e.g. rsync -avzW)
to turn this off.

I don't know objectively how much difference
this makes but it seems reasonable.
