Maybe your older SuSE installation uses the insecure version 1 of the
SSH protocol. I have experienced some speed problems with the more
secure (and thus probably more checking overhead) version 2 of the SSH
protocol, but only in connection with with erraneous switches that split
large packets.
Also, please check that you have switched compression ON in both cases,
using either the Compression=yes config statement, or -C as option to
scp.
