No-one minds if you repost important questions.

Bad latencies are usually due to contention over CPU. Windows
typically is much worse at this than Linux. Check what's running, try
killing anything that looks greedy. And you also need to make sure
your box has enough cores, which is one per 0MQ thread plus one per
0MQ context (for the i/o thread).
