[rabbitmq-discuss] RabbitMQ odd behaviour

I've been seeing some odd slow downs in RabbitMQ and I think it's also
possible to see them with unmodified ProducerMain and ConsumerMain. My
producers managed to publish about 18k messages/second but my consumers
only managed to read at about 1k messages/second. To replicate this run
ProducerMain and ConsumerMain at the same time and you get a good rate of
about 17K messages/second. But if you run ProducerMain until it finishes
(it gets 18K/second) and then run ConsumerMain, ConsumerMain only gets
about 1K messages/second.

Is this normal or is there something odd going on?
