Linux has a pretty efficient TCP stack, unless one bypasses the TCP/IP
layers when connecting over localhost pipes will have fundamentally
less work to do i.e. just copy in to the kernel, copy out of the
kernel - or for larger transfers the kernel can map the destination
buffer into the OS and copy directly.
