Indeed, i encounter the same kind of problems... I think you have a lot of
small files in each directory. This cause a very inefficient transfer.
The files are >5Mb and there are about 12 to each directory.
I answer your private mail on the BTS (to keep track of things).
The 3500/350 kbps explains me why it takes so long (hours compared to 15 min
in my case).
However, i am a bit suprised that transfering several files at once is
longer than transfering only one. I was thinking that you get a better time
transfering more file on a LAN and that it makes no difference transfering
on a slow link...
Do you have any idea ?
Beside this, i agree that a limit should exists, and i think upstream author
will agree too. Moreover, the solution seems pretty easy to implement.

Concerning,
I am not talking about syncing per se. I am talking about the first
time directories are transferred.
You alway sync with unison... It is a file synchroniser ;-) Even the first
time it is syncing.
Anyway, i hope that i have understand your problem. Here is the solution i
will propose to upstream:
* implement a flag/option max-simultaneous-file-transfer which will limit
the number of file transfered in parallel
* document that this option help to speed up transfer on slow link
* document that this option can reduce the risk of an interruption/resume by
processing a more "step-by-step" transfer, since after having finished to
transfer a unit you won't loose it after resuming.
Do you agree ?
