This is all true and I support your hashing patch and all of that.

But if we really want TCP over loopback to go fast, there are much
better ways to do this.

Eric, do you remember that "TCP friends" rough patch I sent you last
year that essentailly made TCP sockets over loopback behave like
AF_UNIX ones and just queue the SKBs directly to the destination
socket without doing any protocol work?

If we ever got that working, tbench performance would become
impressive :)
