I think "communication through files" is misleading.
That file is special, it is a named pipe (or named FIFO...). Just like
/dev/zero and /dev/null, and many of the other files in /dev. The
pipes always transfer data through memory.
I would hazard a guess that named pipes and anonymous pipes
are implemented using the same code. The difference is
how the connection is established.
UNIX vs INET is another story. On loopback, I guess INET would
easily achieve 100MB/sec, and I think UNIX domain sockets
would be faster still.
