I'm fairly new to rabbitMQ - one of the tests I did was to read 1000 messages from rabbitMQ server running locally vs. reading 1000 messages from another server (using .NET client).<br>
<br>
Performance was approx 1000 per second connecting from the same server, vs approx 200 p/s connecting from another server (single-node broker).<br>
<br></div>
What would the bottleneck be here that's limiting the reads to 200 p/s? My guess would be the network hardware.<br>

What network bandwidth do you have?<br>
<br>
And how exactly are you reading messages?<div class="im"><br>

Are there any tricks with setting up or connecting to minimise read times?<br>
</blockquote>
<br></div>
Are you using basic.get? If so then the throughput will be determined by the network latency, since basic.get incurs a full network round-trip per message. To avoid that use basic.consume to set up asynchronous "push" delivery that streams messages to the client.<div class="im">

And what sort of performance benefits can there usually be realized for every node added to a cluster?<br>
</blockquote>
<br></div>
That very much depends on your routing topology. At one extreme, if you have a single producer sending messages to a single consumer then adding nodes will not help at all. At the other extreme, if you have many disjoint streams then near-linear scalability is achievable.<br>
