[rabbitmq-discuss] Lower delivery rate than publish rate - why?

Did you ever find an answer to this question? We are encountering virtually
the exact same problem.

We have a variable number of servers setup as producers and consumers and
see our throughput drop to zero on a periodic basis. This is most severe
when there are a few hundred thousand messages on rabbit.

Did you just drop Rabbit? Ours is running on an m1.large instance with RAID0
ephemeral drives, so size and performance of the disk subsystem is not an
issue (we are still in beta). We have spent untold hours tuning our sharded
mongodb subsystem only to find out that it is only being 25% utilized (at
least it will be blazing fast if we ever figure this out).
