A MCM with no external memories is as fast as a developer board.

The devboard (and MCM) have 16-bit memories. With 32-bit memories
you get the higher transfer rates.

I don't know.

What custom hardware?
What about response time, how fast is it possible to send 1kbyte
from a linux box to etrax and receiving 1kbyte back?
