Rsync has a bwlimit argument which helps here. Note that rsync copies the whole file on what it considers local storage (which can be mounted network shares) ... this can cause a real slowdown.
It won't help on the initial copy, but look at the - I think it is - --in-place option.
It won't help with the "read and compare", but it only writes what has changed, so if a big file has changed slightly, it'll stop it re-copying the whole file.
