You're comparing apples to a factory that can process apples into
juice at the rate of millions a second.

For that extra latency in 0MQ you get things like message batching,
asynch i/o, routing patterns. The cost could be brought down (see
Martin Sustrik's nano project, which brings it way down) by
redesigning the 0MQ internals.

Having said this, it's probably worth taking a profiler to 0MQ and
seeing if the critical path can't be improved somewhat.
