[rabbitmq-discuss] Subscription Performance

[Marcos Torres]

Simon,

I'm using the .NET library, specifically the EventingConsumer. I'm not
setting the prefetch count, I will look into that.
Also, I will start doing some performance with PerfTest as suggested.

Regarding Consumers, we have 1 per queue, that's because we handle a lot
(700) of queues. If increasing the Consumer count will have direct impact
in the delivery, I can explore into that but I cannot match the Producer
count, that's for sure.

Thank you.
