I stumbled over pretty much the same issue on Linux: http://issues.apache.org/activemq/browse/AMQ-905
I don't send msg transactionally, but I consume them like that. For sending msg the only way I could improve performance with a single producer thread is by specifying jms.useAsyncSend=true, but I'm not sure of the significance of that parameter. As for message consumption, I haven't come across a quick fix as yet. How are you able to consume messages so fast in a non-transactional way ? I'm using jencks and message driven pojos but couldn't make it consume any faster than 11 msg/second. kaipa wrote: > > Hi, > > I've read through archives and found that some people experience the same > problem but there were no solution.
