Given that the REs communicate over internal ethernet, I fail to see the
relevance of CPU clock speed in the whole equation.

Or is my technical information about the dual RE interaction wrong?

If my assumption is correct, and the REs talk to each other only via
ethernet and userspace processes... could you give us some insight about
the possible problems faced with interacting REs with different speeds?

I'm curious from a technical POV, really. Perhaps (for sure) I'm missing
something, it's not obvious to me.


Best regards,
