How to improve speed of a single file transfer over an unstable link?

[Scott C. Kennedy]

According to the man page "--append ... implies --partial (since an
interrupted transfer does not delete the file), but conflicts with
--partial-dir and --delay-updates."

So, I'm now almost 56% finished, and my dropping KBps transfer speeds are
now back up to the low 40 KBps!!! :)
