So the consumer apps are constantly being terminated, started, then they
connect and consume
messages (I assume using basic.get)? That's far from being very efficient,
RabbitMQ was
really built with long-running apps in mind.

Plus, with basic.get and immediate processing you get one message at a
time. With "push API"
consumers it can be multiple messages at once. See
for example.

I don't really know what to recommend besides at least not reconnecting all
the time. AFAIK php clients
only support basic.get and not "push" deliveries, neither a long-running
PHP process can offer any
way of concurrent processing.

You can try fetching multiple messages before you process them.
