@whaley, those are good things to consider. I'm beginning to suspect serialization. The messages are probably 2k Bytes max, but it does include a hash table (typically containing 2-3 items in the table!).
The network is local, two machines on the same switch, or sometimes sender and receiver are on the same machine, so I'm suspecting it's not network latency. -- View this message in context: http://activemq.2283324.n4.nabble.com/Slow-and-fast-messages-tp3660295p3710392.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
