As written to Corinna, 32-bit i686 openSUSE 11.2 Linux fully patched with
preinstalled openSSH 5.2.
Few MB, or 1.X MB. example.org is behind an ADSL line which is ~12 Mbit/s in the
direction where I'm trying to copy and ~0.6 Mbit/s in the opposite direction.
Note that with 20100328 I sort of "immediately" get the SSH debug trace, whereas
there is no output at all with 20100331. (on Windows 7 Professional 32-bit
German which itself sits on a 100 Mbit/s firehose). 12 hops, 48 ms (the first 10
hops take 7 ms, 11 hops 14 ms, then the typical DSL interleaving on the last hop).
