What kind of system is that?  (CPU, memory, OS, anything else

I attempted to reproduce your result on a Linux box (1.8GHz celeron)
but got the opposite result which is more along the lines of what you'd
expect.  The first is a file of zeros, the second is from /dev/urandom:

$ scp -C /tmp/50m localhost:/dev/null
50m                                     100%   50MB   7.1MB/s   00:07
$ scp -C /tmp/50mr localhost:/dev/null
50mr                                    100%   50MB   2.0MB/s   00:25
