At the risk of stating the obvious, is there any way you can break
your datasets into smaller pieces? Then, you could start several
rsync processes in parallel - one for each piece, possibly using
separate Internet connections.<br>
<br>
As Kevin says, I'm sure there is no direct relationship between
rsync and scp - they are two separate transfer "protocols", but the
above might get around whatever bottleneck you are running into.<br>
<br>
If rsync is slow, then any other protocol (taking the same path)
will probably be just as slow. You can't get a wider pipe by
changing faucets.<br>
<br>
I don't know much about networking, but if you could use network
diagnostic tools like ping and traceroute to find the actual
cause(s) of the bottleneck (without getting accused of security
violations), then you might be able to find a solution. E.g. maybe
you could arrange to send your data somewhere closer first with
better bandwidth and use their connection (hopefully faster as well
- with their permission/service agreement) to send it the rest of
the way.<br>
