There's a property called Piggyback mode. I don't know if that is applicable to your case, but it has to do with grouping of messages. Worth a look. It wasn't working properly for me.

I have made a PR for a possible fix here: https://github.com/apache/flex-blazeds/pull/2, however we are not very familiar with the codebase and we'd appreciate some feedback on if we have the right approach. The issue we found occurred when a single client has multiple subscriptions (multiple mx.messaging.Consumers on the Flex side), using the same polling channel, which is configured like this: <channel id="my-secure-polling-amf" type="mx.messaging.channels.SecureAMFChannel"> <endpoint uri="https://foo.bar:443/appName/messagebroker/amfpollingSecure"/> <properties> <polling-enabled>true</polling-enabled> <polling-interval-seconds>1</polling-interval-seconds> </properties> </channel> When a poll hits the server, it ends up calling FlexClientOutboundQueueProcessor.flush() on the server. It doesn't pass a MessageClient as an argument, which (according to the javadoc on that file) should mean that it will flush messages for all clients. But instead it finds the first message in the queue and flushes all messages that have the same MessageClient as that one. If a user has 10 consumers with queued messages, it will have to poll once per consumer, which means 10 polls and 10 seconds to clear the queue. The change in my PR will cause it to flush the entire queue each time, so you will get all your data in a single poll. -- Peter Hall Platform Architect [logo]<http://www.algomi.com/> ALGOMI LIMITED One America Square 17 Crosswall London EC3N 2LB Tel: +44 207 954 4543 Mob: +44 779 109 6899 www.algomi.com<http://www.algomi.com/> [http://www.algomi.com/img/apps/fintech2015.png] This email and its contents, including all accompanying communications and attachments, is strictly confidential and only for the intended recipient(s).
