Hi Lars, I am using the servicemix version 3.2.1 . I have a doubt here. The servicemix load balancing feature is provided by apache mq. I have read the documentation of apache MQ and it says that, load bancing is done by splitting the total load into equally among servicemix instances. If they are using round robin algoritham, then for 10messages how will they distribute the load?
