I used a completely different approach that allows parallel but not async processing. Multiple [analysis engine+cas] pair objects pre-instantiated into into a threadsafe pool running behind a web service interface. We can fully saturate a single ctakes server process using multiple client processes talking to that API each working synchronously and arriving at an overall speed of 10-15 6K notes per second on a single server process.
I haven't used AS but it looks as if that middleware could have too many moving parts for our needs. They would generate many wakeups and context switches adding undesired latency as a request makes its way to the server. I'm assuming that in AS, the broker and the MQ are separate processes and not just in-process subsystems to the ctakes server process. Is that right?
