Very slow on subscribe

Hi,

I trying to use this library with jBoss HornetQ 2.1.2 final with STOMP connector. 
In test script, i have more them 9000 msg/sec to publish (900 byte string, random JSON object),
but only 20 - 50 msg/sec to subscribe (!) its very slow...what? Server is small EC2 instance without any other system loading. Node is 0.2.
