My understanding was that the effective rate is 10Mb/s, with only a few usec latency for small messages. How are transputers where the topology and application are fixed, messages are short, and the critical factor is end-to-end delay? What are the limits on link distance, and is there some kind of repeater (besides another transputer)?
