Does Firewire get lower latency, or just better throughput?

What about USB 2 if/when freebob supports it?

And just to be clear - if I run jackd -r 48000 -p 64 -n3, is it
correct that the one-way latency in seconds is 64 * 3 / 48000.0 =
0.004?  So round-trip latency is twice that?
(Plus any converter overhead of course.)
