basic.get isn't inherently slow; it's the latency that's the killer. 
Fetching messages one-at-a-time with basic.get limits the throughput to 
1/2*roundtrip_latency. By contrast, the throughput achievable with 
basic.consume is only bounded by network bandwidth and the performance 
of the endpoints.
