Class com.hazelcast.topic.impl.TopicProxy#publish serializes the message even if the message is never sent due to no subscribers. This is very inefficient at scale. For example, a producer periodically publishing on 100 topics of which typically only 10 have subscribers.

In the case of non-global-ordering and non-client use, the implementation should defer serialization until it has established that there are subscribers.
