Works for me too. Rates for small files are often silly.
In addition to encryption it can support compression (protocol version 1 only).
scp -C -r foo@xxxxxxx:/myfiles .
For compression you trade CPU cycles for bandwidth. Often on a local net
compression can slow things (depends on the data).
Inspect config files... o $HOME/.ssh/config and /etc/ssh/ssh_config with
/etc/ssh/sshd_config can alter behavior in ways you do not expect because
the flag was set there not on the command line.
-q Disables the progress meter.
-l limit Limits the used bandwidth, specified in Kbit/s.
If you are transferring a file in. Do not ignore the ability to
do arithmetic in a second window.
ls -l; sleep 60; ls -l

/dev/null the ultimate in secure storage.
