What kind of CRACK are you smoking? 10mbit ethernet will move 1.2MB/s,
100mbit ethernet will move 12MB/s, and 1000mbit ethernet/fiber will move
120MB/s. There is no 'push really hard'. 

These are real numbers that I see *every day* on a real network, there
is no 'i get a better signal with this monster cable gold plated
ethernet so my network goes faster' when it comes to ethernet, it's
either there (full speed) or it isn't (framing errors and collisions
aside).

The overhead with SSH is CPU, the actual encryption data isn't much
larger than the original unencrypted data.
