Hi Dom,

8Mbit/s not unreasonable for a single TCP stream across the
Internet, but with gandi.fr being only about 11ms away I would have
indeed expected a little more.

As Alan says it may be due to disk speed or rsync compression at
either or both ends.

Do you have an example of a large file at gandi.fr that we can
dowload with a simple TCP protocol like HTTP so that rsync can be
taken out of the picture?

FWIW, ftp2.fr.debian.org is ~17ms away and:
