That is irrelevant. Persistent messages sent to durable queues *always* 
get written to disk unless they can be sent to an auto-ack'ing consumer 
immediately.

The next rabbit release contains an optimisation s.t. when messages get 
ack'ed before they have been written to disk then they won't be written 
to disk.

The only thing slightly strange about what you have reported is the high 
write count. Any chance you could give RabbitMQ 2.6.1 a try?
