I haven't done UDP bandwidth testing--I need to check how lmbench did it for the unix socket and do the same for UDP. Local TCP was far slower than unix sockets though.
That result is system specific and depends upon how the data and datastructures hit the cpu cachelines in the kernel.
TCP bandwidth is slightly faster than AF_UNIX bandwidth on my sparc64 boxes for example.
I've seen that their are the same on linux.I tried to to do AF_UNIX instead of AF_INET internally to boost perf, but to no avail. Makes you suspect that the loopback device actually create an AF_UNIX connection under the hood ;-)
