Mark,

What do you mean by "TCP over Unix Domain Sockets" ??
I think Unix Domain Sockets could be an alternative for TCP (or UDP) if you
don't need inter-machine connectivity.
But TCP 'over' Unix Domain Sockets ?

Julien is just saying that UDS might be faster than loopback TCP, but
probably not much faster than loopback UDP.
