Your intuition would be wrong. ;)

Un-tuned TCP with GigE is nowhere near as fast or as consistent as
Firewire. In fact, you might find even Firewire 400 outpeforms it.

Remember that even doing the TCP checksums @ 1Gbit can tax a CPU.
Hence the existence of ToE GigE NICs.

But don't take my word for it: get two machines and do some
back-to-back tests ;)
