I am not familiar with internal memcached architecture, however, I would
suppose it works in a synchronous fashion, i.e. client asks for an
object and waits for the object to be delivered. There's little 0MQ can
do to optimise that - whatever you'll do the latency will always be 2x
TCP latency (a roundtrip) and throughput will be 1 / (2x TCP latency).
What 0MQ is good for is high-performance asynchronous non-blocking
messaging, i.e. the scenarios where messages are pipelined over the network.
However, if you have any idea how memcached can benefit from such a
scenario, it should be easy to plug it in.
