>
> SJMSComponent effectively ignores setConnectionCount()
> This is because the JmsProducer, by default, pre-populates sessions+producers
> on Producer.doStart(), which is called by the CamelContext in a single thread
> and the way the ConnectionFactoryResource is configured, it returns the most
> recently idle connection (So really it always returns the first connection
> opened).
> This patch attached makes the ConnectionFactoryResource effectively return
> connections in a round-robbin. Unit test attached in included.
> This is important because TCP has a certain overhead per socket which makes
> it impossible to achieve much more than 6~ messages a second, regardless of
> the CPU and IO resources available to a broker. To fully utilize a broker
> multiple connections must be opened.
> This is also important if your ConnectionFactory represent a cluster (Like in
> the case of HornetQ), where subsequent connections are balanced across nodes
> in the cluster.
