ActiveMQ has quite a few transports.  The fastest is the vm in-memory  
transport.  You select it by specifying a vm:localhost?async=true URI  
in the resource adapater or broker connector configuration.

Unfortunately there's a bug in released activemq versions with vm  
transport that can produce a deadlock when used with transacted  
message delivery.  See https://issues.apache.org/activemq/browse/ 
AMQ-1438.
