Using modest hardware I'm able to send and receive a few dozen small
durable messages per second using consume() and recv() in Net::RabbitMQ,
with prefetch_count set to 1 and client-side acknowledgements.
Raising the prefetch count should improve throughput significantly.
You could also compare the performance of the Java client using
MulticastMain to confirm that your infrastructure is capable of better
The delay you report falls within the range of a DNS timeout. Make sure
your throughput is not held back by name resolution.
