Subject Re: Camel routing poor performance vs VirtualDestinations and Topics
Date Tue, 31 Mar 2009 21:51:31 GMT

Hi.

I'm using AMQ 5.2 (apache-activemq-5.2.0-bin.tar).
The camel code is in a java class of my own package
(cl.niclabs.activemq.camel), loaded at the startup in the AMQ's xml config
with this code:

<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring">
		<package>cl.niclabs.activemq.camel</package>
</camelContext>

You can download my configs here: 
http://www.nabble.com/file/p22815567/activemq-tests.tar.gz
activemq-tests.tar.gz 


So, you say that using JMS transactions should rise the camel routing
performance near the VirtualDestination one, that's all?

Thanks for your time.
