SubjectRe: anyone ever done multicast AF_UNIX sockets?
   From: Chris Friesen <>

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.
