There's no inherent cost to having more than one connection in any
network application.  The cost of having memcached on localhost vs. a
remote box is essentially your network latency.  Some client-server
apps like MySQL can use pipes when talking to localhost and avoid the
overhead of TCP sockets, but memcached always uses TCP sockets, so
that isn't a factor.
