Hi,
My call to ActiveMQSession.createConsumer is very slow, taking up to 2
seconds to responde.
That sounds like a slow internet link - or maybe the broker is overworked?
The client and server are separated by an internet connection.
The broker is being fed by a single producer on the same machine of the
broker.
Debugging the client code I see AMQ sends a synchronous message to the
broker with the ConsumerInfo. And this is blocking the client. My
application needs to subscribe to ~50 topics, but taking more than a minute
to do that is unacceptable for me.
Is this performance normal?
No - its very slow
Is there any tweak or test I could make?
Pretty much all request-responses with the broker are about the same
in terms of time.
Do you need any more info on my configuration?
My debug call stack is below.
You could try subscribe to many destinations in one go using composite
destinations...
http://incubator.apache.org/activemq/composite-destinations.html
other than that all you can do is investigate your
network/hardware/firewall/proxies to see why request-response over
your network is so slow
