You might want to try hooking up a profiler to the server JVM and see what method calls the JVM is spending most of its time in to pinpoint exactly where the performance is slow.

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Selector, Transport
>    Affects Versions: 5.13.2
>            Reporter: Matt Ho

> Here is the scenario:
> 1. Start a standalone activemq server (memory persistence)
> 2. Enqueue 3000+ message to a queue
> 3. Dequeue by message selector, and the performance is REALLY bad.
> It seems like MessageConsumer is waiting MessageDispatchChannel to get all the messages from server. Can you fix it in the following updates?
