I try to rsync a lot of data over a long distance AU to UK and get a slow
data rate because of the known slow scp performance over long distances.
Would it be possible with rsync to run multiple scp process at the same time
?
Thank you
Markus

rsync does not use scp in any way.

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.
As Kevin says, I'm sure there is no direct relationship between
Hi Kevin,
but rsync uses ssh doesn't it ? Are there any tuning options for buffers
to deal with the tcp SYN SYN-ACK delay ?
Thank you

You can use the HPN enhancement patches for ssh. They do make a big
difference: http://www.psc.edu/index.php/hpn-ssh

With the SSH-HPN you can achieve over 200MB/sec. Depends on your latency and
packet drops but you should certainly try a modified ssh/scp with rsync. Also
are you using compression with rsync -z? That's an area that could be multi
threaded.
